Description

Field of the invention

The invention relates to a system for the modular retrofitting or supplementing of an optical device, which is designed to display an image of a distant scene and to be retrofitted with a laser distance measurement of a possibly small object from the distant scene, especially for long distances.

Background of the invention

Currently, optical devices with integrated laser rangefinders, so-called Laser Rangefinder (abbreviated to "LRF") are available, especially for hunting purposes. A laser rangefinder typically includes a laser transmitter and a laser receiver, each with associated optics for the emitted and received laser beam.

An example of a remote optical device with integrated laser rangefinder of the applicant are the binocular Victory RF binoculars and the riflescope Victory Diarange (see www.zeiss.de).

In the imaging optics of the Victory RF binoculars, through which the user views the magnified image of the distant scene under consideration (sometimes referred to as the "vision channel"), a laser target is displayed which the user directs to an object in the scene of interest Distance measured and displayed. The Victory RF has an optical magnification of either 8x or 10x. As a result, the user sees the objects in a distant scene with a correspondingly large magnification. Thus, if a telematic device with such an optical magnification is equipped with a laser rangefinder, this typically requires a precise adjustment between the imaging optics of the far-optical device and the laser beam of the integrated laser range finder, so that the laser with its integrated laser optics also magnified just that Object in the distant scene, which is targeted with the laser target mark in the imaging optics. As a result, laser range finders in optical-magnification telematic devices are typically factory-integrated and precisely adjusted at the factory.

From the WO 2012/081995 A1 a rangefinder module is known, which can be attached to a portable device, such as a smartphone. The camera of the smartphone records a scene and displays it using the display. A crosshatch will appear in the display and the user will be directed so that the user moves the crosshairs in the xy direction on the screen. Such a user-facing orientation appears to be less precise and tedious for the user. Furthermore, this method seems to be essentially applicable to digital cameras with wide-angle optics. For imaging optics with possibly strong optical magnification, such as in a pair of binoculars or a riflescope this method does not seem to be sufficiently accurate, or an adjustment between the optical axis of the viewing channel and the axis of the laser beam would be at least difficult. For analog remote optical devices, the process is not suitable at all.

General description of the invention

The object of the invention is therefore to provide a system which makes it possible to retrofit or supplement an optical device with a laser distance measurement with high precision, in particular for distant objects.

A further aspect of the object is to provide a system which makes it possible to retrofit or supplement an analogue optical device, in particular a telescopic sight, spotting scope or binoculars, with a laser distance measurement.

A further aspect of the object is to provide a system which enables retrofitting or supplementing an optical device with a laser distance measurement which is quick, easy and convenient for the user to use.

The object of the invention is solved by the subject matter of the independent claims. Advantageous developments of the invention are defined in the subclaims.

According to the invention, a system is provided for the modular retrofitting or supplementing of an optical device, which is designed to display an image of a distant scene and is to be retrofitted with a laser distance measurement of an optionally small object from the remote scene.

The retrofit system includes an optical device having a first imaging optic. The imaging optical device in a general form of the invention may be a digital or analog optical device. Exemplary analog optical devices are analog binoculars, analogue spotting scopes and analog riflescopes, eg for hunting weapons. Exemplary digital optical devices are digital binoculars, digital Scopes, digital riflescopes, smartphones, notebooks, tablet computers, digital cameras or camcorders. In an analog optical device, the remote scene is purely optical, for example, with lenses, mirrors and / or prisms imaged, and the user sees with his eye through the optical channel, the purely optical image. In a digital optical device, sometimes referred to as an electronic optical device, forms the optics on a two-dimensionally resolving image sensor, such as a CCD or CMOS chip. The thus digitally recorded image is processed digitally and displayed by a two-dimensional resolution display, such as a small LCD or TFT monitor, and the user views the thus digitally or electronically generated image on the display. The user views the digitally generated image on the display either directly, for example in the case of a smartphone or a tablet computer, or through an eyepiece, for example in the case of digital binoculars, digital scope or a digital riflescope.

According to the invention, a laser distance measuring module (also called a laser rangefinder module or LRF module for short), which is provided separately by the user and can subsequently be coupled modularly to the optical device, is made available in order to subsequently retrofit the optical device with the laser distance measurement. The laser range finder module has its own housing which can be coupled to the housing of the optical device, in which a laser transmitter with laser transmitting optics for emitting a range finding laser beam, a laser receiver with laser receiving optics for receiving the distance measuring laser beam reflected from the object of the remote scene and an evaluation device, which in response to the emitted from the distance measuring laser beam and the reflected from the object received rangefinder laser beam determines the distance to the object are housed.

The laser distance measuring module further comprises a target device for sighting the object for the distance measurement. In other words, the aiming device for sighting the distance measuring object is associated with the laser range finding module and does not belong to the optical device. That the target device is factory-integrated into or on the laser rangefinder module, and the user acquires the laser range-finder module as a unit with the already integrated target device.

The target device associated with the laser range finder module is factory-adjusted relative to the rangefinder laser beam. The integration of the aiming device in or on the laser distance measuring module and the related factory adjustment already has the advantage that after coupling the laser distance measuring module to the optical device, the user no longer needs to adjust the aiming device relative to the distance measuring laser beam and nevertheless ensures that in fact, the distance of the object targeted by the target device and not another object is measured and displayed. Furthermore, a high precision can be achieved in the factory, so that optical devices with greatly magnifying magnification optics, such as e.g. Binoculars and riflescopes can be retrofitted.

The imaging optics for the optical device is in the state in which the laser distance measuring module is coupled to the optical device, thus in particular a magnifying optics, which causes an optical magnification, which from the distant scene at a distance of 100 meters a field of 30 meters or less at a subjective field of view angle of approximately 22 °. The laser range finding module according to the invention is thus not only suitable for retrofitting or upgrading of mobile telephones with wide-angle to normal lenses, with which typically relatively close objects are to be targeted.

In order to provide the imaging optics for the optical device in the state in which the laser range finding module is coupled to the optical device as magnifying optics for displaying the removed scene with optical magnification, two variants can be provided:
Either i) the first imaging optics of the optical device itself is already a magnifying optic for displaying the removed scene with optical magnification, such as a pair of binoculars or a telescopic sight, or ii) the first imaging optics is upgraded by the laser range finding module to a magnifying optic. For the second variant ii), the laser distance measuring module comprises a tele-set for the first imaging optical system of the optical device, which is automatically placed in front of the first imaging optical system of the optical device when coupling the laser distance measuring module to the optical device and together with the first imaging optical system of the optical device the magnifying optic forms. In this case, the tele-attachment may be rigidly secured to the housing of the laser range finding module and is factory-adjusted relative to the range-finder laser beam. With this second variant ii) optical devices with wide-angle or normal lenses can be retrofitted simultaneously with a magnifying optics and the laser distance measurement, and still can be guaranteed especially in a magnifying optic sensitive adjustment of the rangefinder laser beam and the target device.

Preferably, in the variant i), the first imaging optics of the optical device itself already have an optical magnification, which images a field of 30 meters or less at a subjective field angle of about 22 ° from the distant scene at a distance of 100 meters. In variant ii), the tele-supplement together with the first imaging optics of the optical device causes an optical magnification, which images a field of 30 meters or less at a subjective field-of-view angle of about 22 ° from the distant scene at a distance of 100 meters. To retrofit an optical device with such an optical magnification with a laser rangefinding module does not seem possible with sufficient precision with known LRF retrofit concepts at a reasonable cost.

According to a preferred embodiment of the invention, the laser distance measuring module comprises a separate second imaging optics for imaging the removed scene. The second imaging optics of the laser rangefinding module is thus independent of the first imaging optics of the optical device, which is retrofitted with the laser rangefinder module. In other words, the laser distance measuring module has its own viewing channel.

The second imaging optic of the laser rangefinding module is in particular a magnifying optic for displaying the remote scene with optical magnification, preferably causing an optical magnification, which from the distant scene at a distance of 100 meters a field of 30 meters or less at a subjective field of view angle of approx 22 °.

This embodiment is particularly suitable for digital optical devices, i. optical devices having a first two-dimensional resolution image sensor, e.g. a CCD or CMOS chip on which the first imaging optics images and a two-dimensional resolution display representing the image signal of the first two-dimensionally resolving image sensor to the user. These can be digital binoculars, digital spotting scopes, digital riflescopes, smartphones, notebooks, tablet computers, digital cameras or camcorders. In this case, the laser distance measuring module itself is a complete digital optical device (with or without its own display) and, in addition to the second imaging optics, comprises a second two-dimensionally resolving image sensor, e.g. a CCD or CMOS chip on which the second imaging optics are imaged. This has the advantage that the target device has an electronic target for the rangefinder laser, in short, an electronic target laser, e.g. may include a target circle which is digitally inserted into the image captured by the second two-dimensionally resolving image sensor, and wherein the electronic laser aiming mark in the image is already factory-adjusted relative to the ranging laser beam. In other words, the laser ranging module provides a digital image with an electronically superimposed laser target, and the user can rely on the electronic laser target to coincide with the point of impact of the rangefinder laser beam on the removed but optically magnified object with sufficient precision.

The digital image is preferably transmitted digitally together with the electronic laser target mark and / or the measured distance value to the optical device and optionally displayed with the displayed measured distance value on the display of the optical device for the user. In this case, the superimposition of the laser target mark with the image recorded by means of the second imaging optics of the laser rangefinding module is already factory-adjusted to the rangefinder laser beam in order to precisely align the rangefinder laser beam with the object targeted by the optical device. Thus, since this adjustment is independent of the first imaging optics of the optical device, the adjustment of the electronic laser target in the image relative to the ranging laser beam does not depend on the first imaging optic of the optical device.

The advantages of the invention are particularly noticeable when using a magnifying optics. If, for example, one would aim a far-away object with the wide-angle camera of a mobile phone, this would possibly only be imaged on a few pixels of the image sensor, so that a distance measurement would possibly be inaccurate. When the imaging optics for the optical device in the state in which the laser range finding module is coupled to the optical device is a magnification optical system for displaying the remote scene with optical magnification, also the distance measurement at long distances can be more accurate. For this purpose, according to a preferred embodiment of the invention, the laser range finding module comprises a tele-set for the first imaging optic of the optical device. The telephoto set is placed in front of the first imaging optics of the optical device by coupling the laser range finding module to the optical device and, together with the first imaging optics of the optical device, forms the magnification optics. In this embodiment, the telephoto set together with the aiming device is factory-adjusted relative to the range finding laser beam, and the aiming device of the laser rangefinding module fades or mirrors a laser aiming mark into the teleshoot, such that the displayed or mirrored laser target is imaged by the first imaging optics of the optical device together with the remote scene. This also allows a sufficiently accurate adjustment of the laser target to the actual rangefinder laser beam can be achieved.

According to a preferred embodiment of the invention, the optical device has its own further target device for sighting the object. This further target device of the optical device may be e.g. a retardation, as it can be present in analog riflescopes, analogue spotting scopes, and analog binoculars anyway. Thus, the user only needs the rangefinder laser beam relative to the further target device, e.g. to align the sight of the riflescope, spotting scope or binoculars. For this purpose, the optical device and the laser distance measuring module have directionally adjustable connecting means, by means of which a mechanical adjustment of the optical axis of the distance measuring laser beam to the optical axis of the first imaging optics of the optical device by the user is made possible to those belonging to the laser range measuring module and the factory relative to the Aligning rangefinder laser beam aligned target device together with the rangefinder laser beam relative to the other target device of the optical device. After this alignment, the user no longer needs the aiming device of the laser range finding module and can use the further aiming device of the optical device to sight the object. Using the example of a riflescope, spotting scope or binoculars, this means that the user mechanically connects the laser distance measuring module to the riflescope, spotting scope or binoculars. Then the user can clamp the rifle with the riflescope, spotting scope or binoculars, e.g. in a tripod or a jack. Then the user targets a stationary, far-away object, e.g. a steeple or another striking object. Subsequently, the user adjusts the adjustment mechanisms of the linkage mechanism between the laser range finder module and the binocular or riflescope until the rangefinder laser beam factory-adjusted aiming device of the laser range finding module and sight of the rifle scope, spotting scope or binoculars are matched to be the same location of the remote Target the object. Subsequently, it is ensured that the rangefinder laser beam actually hits the object which the user is aiming with the sight of the riflescope, spotting scope or binoculars, so that the distance measurement is reliable and precise even at long distances or with strong optical magnification.

Preferably, the optical device is an analog optical device, e.g. an analog rifle scope, spotting scope or binoculars with at least one eyepiece. Furthermore, by way of example, the aiming device of the laser distance measuring module can be a sight-and-sight sighting, in particular an open sighting or sighting, possibly a simple refractive optical sighting, e.g. include a simple auxiliary riflescope or a targeting laser. Hereby, the laser distance measuring module according to the invention can be flexibly adapted to the respective optical device and the corresponding requirements for precision and / or cost.

The invention further relates to the laser distance measuring module, which can later be connected in a modular manner to an optical device for displaying an image of a remote scene on the user side. The laser range finding module of the present invention includes a laser transmitter with laser transmit optics for emitting a range finder laser beam, a laser receiver with laser receive optics for receiving the range finder laser beam reflected from the subject of the remote scene, and an evaluator which determines the distance to the receiver in response to the transmitted rangefinder laser beam and the received rangefinder laser beam reflected from the subject determines and, if necessary, displays or provides for transmission to retrofit an optical device with a laser distance measurement for an object from the remote scene.

The laser distance measuring module has a target device for sighting the object for the distance measurement. The aiming device in particular generates an electronic laser aiming mark, e.g. a laser target circle or comprises a target laser.

The aiming device of the laser distance measuring module is factory-adjusted relative to the range finding laser beam so that after coupling the laser rangefinding module to the optical device, the user need not adjust the aiming device of the laser rangefinding module relative to the rangefinder laser beam.

In the following the invention will be explained in more detail by means of embodiments and with reference to the figures, wherein the same and similar elements are partially provided with the same reference numerals and the features of the various embodiments can be exchanged and / or combined with each other.

Detailed description of the invention

1 and 2 show a laser rangefinder module 12 which is connected to an imaging optical device, in this example a smartphone 14 with camera, is coupled. The laser rangefinder module 12 includes a laser transmitter 16 , which has a laser transmission optics 18 a rangefinder laser beam 20 emitted. The rangefinder laser beam 20 gets from a distant object 22 a scene 21 reflected and via a laser receiving optics 24 from a laser receiver 26 detected. One with the laser transmitter 16 and laser receiver 26 connected control and evaluation device 28 determines the distance to the object in a manner of the laser distance measurement basically known to the person skilled in the art 22 ,

The laser rangefinder module 12 has its own imaging optics 30 to represent a scene 21 with the object 22 whose distance is to be measured. The imaging optics 30 makes the distant scene 21 on a two-dimensional resolution image sensor 32 of the laser distance measuring module 12 , For example, a CCD or CMOS chip, which from the control and evaluation 28 is read out. The laser rangefinder module 12 thus includes the components 16 . 18 . 24 . 26 for the laser distance measurement, additionally an own imaging system in the form of an integrated camera 33 comprising the imaging optics 30 and the image sensor 32 and the control and evaluation device 28 , The imaging system of the laser rangefinding module 12 can also be used as - in this example digital - visual channel 36 be designated. The laser rangefinder module 12 Accordingly, it comprises a separate viewing channel from the viewing channel of the smartphone camera 36 , The control and evaluation device 28 processes the digital image of the image sensor 32 and calculates the distance to the object 22 , The laser rangefinder module 12 includes a target device 80 which is an electronic laser target 34 generated. For example, the destination device 80 in the control and evaluation device 28 be integrated, in which the control and evaluation 28 the electronic laser target brand 34 generated. The destination facility 80 is - in this example electronically - factory adjusted to the effect that the laser target is 34 relative to the laser transmitter 16 or the laser distance measuring beam 20 and the visual channel 36 is aligned, so as to ensure that the rangefinder laser beam 20 exactly the object 22 or the spot in the distant scene 21 which of the laser target makes 34 is marked.

The of the laser rangefinder module 12 generated laser target brand 34 can from the control and evaluation 28 digitally into that of the image sensor 32 generated picture 38 to be displayed. Then the picture can 38 together with the laser target brand 34 via a data connection 40 from the laser range finder module 12 to the smartphone 14 be transmitted. In other words, in this embodiment, the digital image becomes 38 for insertion of the laser target mark 34 not about the imaging optics 42 of the smartphone 14 but via the camera 33 of the laser distance measuring module 12 , with their imaging optics 30 and their image sensor 32 So over the view channel 36 of the laser distance measuring module 12 , Thus, it can be ensured that the Adjustment between the laser target generated by the target device 34 and that actually from the rangefinder laser beam 20 object is sufficiently accurate without any adjustment between the laser distance measuring module 12 and the smartphone 14 is necessary by the user.

The insertion of the laser target 34 can be before transferring over the digital connection 40 from the laser range finder module 12 to the smartphone 14 electronically already in the laser distance measuring module 12 but can also be done by transmitting coordinates of the laser target 34 from the laser range finder module 12 to the smartphone 14 done or fixed in the middle of the display 44 of the smartphone 14 be predetermined.

The laser rangefinder module 12 can turn over a data connection 46 by means of one on the smartphone 14 running program, eg an app 48 be operated and / or controlled. The triggering of the laser distance measurement can be done either by a shutter button 49 at the laser distance measuring module 12 or via the app 48 of the smartphone 14 respectively. Optionally, the laser distance measuring module 12 one or more sensors 47 include, for example, one or more angle sensors, a temperature sensor, a humidity sensor and / or an air pressure sensor. The control and evaluation device 28 or the app 48 may comprise a ballistic calculator responsive to the one or more sensors 47 , So with the one or more angle sensors, the temperature sensor, the humidity sensor and / or the air pressure sensor of the Laserentfernungsmessmoduls 12 calculated values of angle, temperature, humidity and / or air pressure calculates a ballistic solution. The laser rangefinder module 12 also preferably has its own power supply 51 in the form of a battery on or off the battery of the smartphone 14 provided.

In summary, the laser distance measuring module 12 over the data connection 40 that from the image sensor 32 recorded image of the scene 21 , the distance reading 50 and possibly the laser target 34 to the smartphone 14 transfer. The data connections 40 . 46 are preferably radio links, eg Bluetooth, WLAN or NFC, so that the transmission of the image signal, the laser target 34 and the determined distance measurement value 50 , as well as possibly the determined measured values and / or the calculated ballistic solution via the radio link 40 to the smartphone 14 done and this together on the display 44 of the smartphone 14 being represented. The control and transmission of the required information is therefore preferably via radio links, but the data connection can also be wired depending on the application. It can be seen that the smartphone 14 merely serves as an example of an optical device and the optical device, for example, a notebook, a tablet computer, a digital camera, a camcorder or the like can be.

Referring to 2 can the laser rangefinder module 12 a mechanical fastening device 52 include, by means of which the smartphone 14 on the laser rangefinder module 12 is attached. Alternatively, the laser distance measuring module 12 also detached from the smartphone 14 and only via the data connections 40 . 46 , in particular radio communications, data technology with the smartphone 14 be connected. Advantageously, there is no precise adjustment between the laser range finder module 12 and the smartphone 14 necessary by the user.

Referring to the 3 and 4 includes the laser rangefinder module 12 according to a second embodiment of the invention, a tele reference 54 , The laser rangefinder module 12 According to the second embodiment, as in the first embodiment, a laser transmitter 16 with laser transmission optics 18 and a laser receiver 26 with laser-receiving optics 24 , The tele-conversion 54 is one in the laser rangefinder module 12 integrated magnifying optical system, eg a glass attachment for optical enlargement of the scene 21 , Referring to 4 In the second embodiment of the invention, the image becomes 38 on the display 44 of the smartphone 14 unlike the first embodiment, not by an image sensor of the laser range finding module 12 but through the image sensor 56 of the smartphone 14 generated.

Referring to 4 make up the tele-feed 54 the laser range finding module and the imaging optics 42 of the smartphone 14 together an imaging optics 58 with optical magnification. About the data connection 40 becomes the by means of the components 18 . 20 . 24 . 26 . 28 determined distance measurement value 50 over the data connection 40 from the laser range finder module 12 to the smartphone 14 transfer.

The smartphone 14 looks in this example, so to speak "analog" through the Televorsatz 54 with the imaging optics 42 of the smartphone 14 , The attachment of the smartphone 14 on the laser rangefinder module can be done by means of a (metal) ring on the smartphone 14 is glued and in which the optics of Televorsatzes 54 is screwed. Alternatively, other mechanical clamping devices may be used.

In this example, the destination device generates 80 of the laser distance measuring module 12 a laser target 34 which in this example in the Televorsatz 54 is faded in or mirrored in, so that the image sensor 56 of the smartphone 14 the scene 21 and the laser target 34 together about their own imaging optics 42 sees. By means of the control and evaluation device 28 can the laser target brand 34 can be turned on and off, and it may possibly the brightness of the laser target 34 be set.

Referring to 5 is the tele reference 54 preferably designed as a Galilean telescope. Advantageously, a compact design is possible hereby possible; no inversion system / prism reversing system is needed, and the construction is inexpensive. The laser target brand 34 is in the example shown by a light source 62 , eg an LED or a laser diode. The laser target brand 34 is by means of a diaphragm 64 fades in, goes through an optic 66 and is from a beam splitter 68 , which makes a 95% / 5% division, in the beam path 70 of the tele-conversion 54 mirrored. Here, 95% of the light of the scene under consideration is transmitted and 5% of the light of the LED in the beam path 70 reflected in it. The optics 66 for the laser target brand 34 does not necessarily have to be realized from lenses or mirrors, if necessary, a holographic optical element (holographic optical element, short HOE) is sufficient.

The factory adjustment of the target device 80 generated laser target brand 34 relative to the telesource 54 or to the beam path 70 can be relatively easy by xy-adjusting the light source 62 respectively.

6 shows a variant of the Televorsatzes 54 in which the laser target is over a thin glass plate 72 is reflected. Otherwise, the construction corresponds to that in 5 ,

Referring to the 7 to 10 is a laser rangefinder module 12 as a clip-on module for an analogue long-range optical device 74 , eg a riflescope, spotting scope or binoculars. The laser rangefinder module 12 is by means of adjustment 76 . 78 on the remote-optical device 74 attached and is about the adjustment 76 . 78 horizontally and vertically (x, y) adjustable so that the rangefinder laser beam 20 with the optical axis 79 of the far-optical device 74 can be brought into agreement.

The laser rangefinder module 12 has a destination facility in this example 80 in the form of their own sight or auxiliary target device, which, for example, as a sight-and-grain sighting 82 ( 9 ) or as an auxiliary riflescope 84 ( 10 ) may be formed. Alternatively, a targeting laser as the target device 80 of the laser distance measuring module 12 be used. The destination facility 80 of the laser distance measuring module 12 is factory-set relative to the rangefinder laser beam 20 adjusted. In other words, the adjustment is between the target device 80 and the rangefinder laser beam 20 factory fixed.

The user can use the laser rangefinder module 12 by means of the adjusting device 76 and 78 relative to the far-optical device 74 align by the user the rifle 86 at which the far-optical device, in particular riflescope 74 is attached to a Anschussbock 88 clamps and then a far away object 22 For example, a spire with both the target device 80 , eg the sight-and-grain sighting 82 or the auxiliary riflescope 84 of the laser distance measuring module 12 as well as with the reticle 90 of the far-optical device 74 targeted and the destination facility 80 and the reticle 90 by adjusting the mechanical adjustment 76 . 78 in agreement. Subsequently, the user needs the target device 80 not anymore, but as usual with his eye 91 through the far-optical device 74 aim his target, and it is now guaranteed that the rangefinder laser beam 20 that with the reticle 90 targeted object 22 so that the distance measurement with respect to the targeted object 22 correct is. The mechanical recording with the adjustment 76 . 78 on the remote-optical device 74 is preferably parallel to the optical axis of the far-optical device 74 and has sufficient accuracy for the sighting of the target after the above-described alignment of the optical axes has been performed once.

The laser rangefinder module 12 has a corresponding housing 92 on, on which the target device 80 is attached and in which of the laser transmitter 16 and the laser receiver 26 with associated optics, 18 . 24 are housed. The housing 92 of the laser distance measuring module 12 also houses the control and evaluation 28 , which performs the calculation for distance measurement and possibly the ballistic solution and the laser transmitter 16 and the laser receiver 26 controls. Furthermore, the laser distance measuring module comprises 12 a power supply 51 , eg a battery, so that the laser rangefinder module 12 can be operated independently, one or more control buttons 100 , in particular for triggering the laser distance measurement and a display 98 which the distance reading 50 displays. Alternatively or additionally, the distance measurement value 50 via a data connection 40 , in the present example in the form of a radio link, to the far-optical device 74 be transmitted. The distance reading 50 can then be on an optional external display element 102 of the far-optical device 74 are displayed and / or in the beam path of the long-range optical device 74 fade in, eg in a lower segment of the reticle 90 so that the user receives the information from the laser rangefinder module 12 measured distance measured value 50 directly in the field of view when aiming the target object with the long-range optical device 74 gets displayed.

11 shows a reticle 90 in which in the lower segment of the laser distance measuring module 12 measured distance reading 50 is displayed.

If the far-optical device 74 is a riflescope, optionally the set elevation value over the data connection 46 from the rifle scope 74 to the laser rangefinder module 12 be transmitted, for example, optically, electronically or via radio. The elevation value transmitted by the scope to the laser range finder module may be included in the calculation of the ballistic solution. If adjusting the reticle 90 is changed after the alignment of the optical axes, an automatic tracking of the alignment of the optical axes, for example by piezoelectric elements take place.

It will be apparent to those skilled in the art that the above-described embodiments are to be read by way of example, and that the invention is not limited thereto, but that it can be varied in many ways without departing from the scope of the claims. It is also to be understood that the features, independently as they are disclosed in the specification, claims, figures, or otherwise, also individually define essential components of the invention, even if described together with other features. Further, features of the embodiments described above may be interchanged and combined, and the embodiments described in the context of smart phones, digital cameras, riflescopes, spotting scopes, binoculars, etc. may also be applied to other optical devices.
