Abstract

Angle mirror for observing the surroundings of a vehicle with a viewing part (4) and a display (1) for displaying additional information, wherein an optical lens (2) between the viewing part (4) and the display (1) is arranged, characterized in that the display light path (8) and the ambient light path (9) intersect at an observation point (S) outside the angle mirror, so that the environment can be observed at a first viewing angle (α 1 ) and the display can be observed at a second viewing angle (α 2 ).

Description

  • The invention relates to an angle mirror for observing the surroundings of a vehicle with a viewing part and a display for displaying additional information, wherein an optical lens between the viewing part and the display is arranged.
  • Angular mirrors are preferably used in military or armored vehicles and serve to observe the vehicle environment from the protected interior of the vehicle so that the corresponding observer neither leave the vehicle nor stretch his head out of the vehicle and thus expose himself to danger. Often they serve as a replacement for windows.
  • Angle mirrors have beam deflectors that direct the light rays of the environment inside the vehicle. In this case, usually two reflection bodies are arranged, for example in the form of prisms or mirrors, such that an incident light beam is reflected by the first reflection body, also called the look-ahead part, onto the second reflection body, also called a viewing part, and from there further into the interior of the vehicle or is directed to the observer. In this case, an optical medium, for example a glass body in the form of a prism or a cylinder, is usually arranged between the viewing part and the viewing part.
  • In military vehicles, the look-ahead part is usually located outside the armor or outside the vehicle, the optical medium is usually arranged in the armor or is guided by it. The viewing part is usually arranged inside the vehicle, so that light rays from outside or from the environment can fall into the interior of the vehicle, without a direct line of sight exists.
  • The problem with looking through an angle mirror is that during the observation of the environment no vehicle fittings can be observed. This leads to problems especially when the driver of the vehicle drives the vehicle by means of an angle mirror, since he constantly has to direct his gaze and his attention to the vehicle fittings and thus at least for a short time has to disregard the vehicle environment.
  • It has therefore been found to be useful if a display is integrated into the angle mirror on which, for example, additional information, as can also be seen on the vehicle fittings, are displayed.
  • The DE 10 2013 106 551 B3 describes an angle mirror with an insight, a view, a vertically arranged on the angle mirror display, a coupling lens and a deflection mirror designed as a beam splitter. These are arranged so that the beam path of the display is superimposed on the beam path through the view at the beam splitter.
  • The DE 696 18 809 T2 relates to an angle mirror in which light rays from the environment and light rays from a display are superimposed with a beam splitter inside the angle mirror.
  • In the DE 102 04 976 A1 a periscope is described in which additional information is superimposed on the external image.
  • The US 2014/0085716 A1 discloses a periscope with a selectively movable between two positions reflector for switching between a pure optical and an electronically generated image.
  • In the US 2012/0099191 A1 A periscope device is described in which a first light-based information is displayed together with a visual additional information of a second light-based information of a projector.
  • The WO 2010/102597 A1 discloses such an angle mirror with a display, wherein in a certain viewing position the display and in another viewing position the environment can be observed. The viewing part is designed such that it is reflective under a first viewing position and thus functions like a part of a normal angle mirror and is transparent under a second viewing position, so that the display arranged behind it can be viewed.
  • A disadvantage of this device, however, is that the eye of the observer must be strongly accommodated when viewing the display, which leads to a great effort especially with constant change between viewing the display and the environment, which can be considered largely without accommodation.
  • Based on this problem, the invention thus provides the task e to provide an angle mirror of the type mentioned, the display can be viewed without or with only a small accommodation.
  • This object is achieved with the features of independent claim 1. Further advantageous embodiments of the invention are part of the dependent subclaims.
  • The fact that an optical lens is arranged between the viewing part and the display, it is possible that an extended image width, which is significantly greater than the distance between the observer and the display results, and the display can be imaged at infinity. The observer can therefore relax and view the display as far as possible without accommodation.
  • Especially when the angle mirror is used in vehicles with strong vehicle movement, such as during fast off-road or in heavy seas, the distance from the viewer to the angle mirror must be very small, so that just then a very strong accommodation of the eye is needed to the contents of the To recognize displays. Sometimes the distance to the display due to the smallest possible depth, be so small that the accommodation width of the eye is no longer sufficient to perceive the display accordingly sharp.
  • The environment of the vehicle is, depending on the distance of the object to be observed, considered with a small accommodation of the eye, so that the eye must constantly change the focus when switching between the view of the lens or on the display and the view from the angle mirror , However, due to the optical lens, the display is displayed at infinity, so that the eye does not have to be re-accommodated, or only slightly recalculated, thus enabling a sharp and relaxed vision.
  • The display can be designed as an electronic display and is preferably not arranged at eye level, but staggered. For this reason, it is sufficient if the viewer only moves his eyes to observe either the display or the environment. A head movement is not needed. This offers the advantage that the observer can press his head against the angle mirror or against a corresponding device, especially in the case of vibrations or impacts, for example because of a vehicle movement, which is why the probability of having to avert the gaze due to rapid movements of the vehicle from the angle mirror, is reduced.
  • Due to the arrangement of the display, however, an oblique view may occur because of which the display is distorted. In addition to the already described accommodation, the optical lens can also compensate for these distortions and display the display as sharply and undistorted as possible. This will be explained below.
  • In the case of the angle mirror, a tube can be arranged as an optical medium between a viewing part and a viewing part. The tube can be formed without a core, ie as a hollow body or with a core, ie as a solid body. The tube can be translucent, light-conducting and / or transparent. It can have both a square and a round base and thus be designed both as a prism and as a cylinder, so that the deflection angle of the incident light rays is substantially 0 ° and there is only a height offset of the light beams. Alternatively, the tube may also be formed as an oblique prism or as an oblique cylinder, so that the height offset of the light beams is superimposed by a corresponding tilting.
  • At the upper end of the tube it is connected to the viewing part and at the lower end to the viewing part. Viewing and / or viewing part can be designed as a prism with a triangular base. In this case, in each case one side of the prism can be formed as a deflection surface on which light is reflected, it being advantageous if total reflection occurs at the deflection surface, so that as far as possible no light is transmitted through the deflection surface or absorbed by it. Alternatively, the display can also be arranged behind a partially transparent body, in particular behind the viewing part, so that the viewing part is arranged between an observer and the display.
  • The tube with inlet and outlook part can monolithic, ie consisting of a solid unit formed. This is particularly advantageous when it comes to a use with strong vibration, so that the input and view parts are geometrically unchangeable connected to the tube. Alternatively, the viewing and viewing section may be separate units, for example, connected to the tube or attached to this or other suitable objects. Alternatively, it is also possible that the angle mirror does not have a tube and the light rays are guided tube-free from the viewing part to the viewing part.
  • The viewing part may have a viewing opening into which the observer looks into to observe the surroundings. The lookout part may have a lookout opening through which light rays from the environment may be incident on the angle mirror. The viewing and viewing parts may have apertures with which the corresponding entry or view openings can be closed. Preferably, the panels are pivotally mounted on the angle mirror or arranged accordingly on the vehicle, so that the panels are selectively pivoted in front of the entrance or the view opening and they can thus be closed.
  • The display can be arranged in the region of the tube. In one possible embodiment the display case on the side of the tube, which lies opposite the viewing opening arranged. Alternatively, however, the display can also be arranged on the opposite side, that is to say on the side opposite the viewing opening, wherein a further deflecting device such as a mirror can then be arranged on the side of the tube opposite the viewing opening.
  • If the display is arranged substantially parallel to the wall of the tube, a small depth can be achieved, which is particularly important when the angle mirror is used in military vehicles, because there the space available is very limited.
  • A light beam incident from the surroundings in the angle mirrors can fall through a viewing opening onto the deflecting surface of the viewing part and be reflected thereon, in particular totally reflected. From there, the light can be directed through the tube onto the deflection surface of the viewing part, where it in turn is reflected, in particular totally reflected and then passed through the viewing opening to the observer. The path taken by such a light beam is also called the ambient light path.
  • According to the invention, the light path, the light beams emitted by the display and guided to the observer, also called the display light path, and the ambient light path intersect at a point outside the angle mirror behind the viewing opening. At this so-called observation point, there may be an observer, who can perceive the light beams of the ambient light path at a first viewing angle and the light beams of the display light path at a second viewing angle.
  • By changing the viewing angle, the vehicle surroundings can thus be observed at a first angle and the display can be observed at a second angle. The head position does not need to be changed.
  • Preferably, the display is not arranged at eye level, so that it comes to an oblique view of the display due to the second viewing angle. The distance of a lower part of the display to the observer is thus smaller than the distance of an upper part of the display, so that the image of the display would be displayed distorted without aids. Among other things, there is a so-called trapezoid distortion, which is also known as Keystone distortion or as Keystone effect, whereby the display is distorted and the corresponding information is very poor or unreadable. Due to the optical lens, which is arranged between the observer and the display and in particular between the tube and the display, these distortions due to tilting of the lens can be compensated for in whole or in part.
  • The image distortion can be due to the oblique view depending on the second viewing angle and thus the position of the display. In order for the optical lens to compensate for the resulting distortions in the best possible way, it can be adapted to the position of the display.
  • In order to keep the depth and also the weight of the angle mirror as low as possible, it has been found to be advantageous if the optical lens is as narrow as possible. The lens is therefore preferably designed as a Fresnel lens. Such a Fresnel lens has a significantly smaller thickness compared with conventional lenses, thereby reducing the depth of the angle mirror.
  • Particularly preferably, the Fresnel lens consists of a central thin spherical or aspherical lens, which is surrounded by ring-like arranged ring lenses. The individual ring lenses can be so narrow that their widths are below the resolution of the human eye. As a result, the lens on the one hand, the screen as sharply as possible, on the other hand, the thickness of the lens is reduced to a minimum. Alternatively, the individual ring lenses can also have transitions, so that there is a progressive power and no perceptible gradations and jumps can be seen even with wider ring lenses, which could affect the sharpest possible presentation.
  • In a preferred embodiment, the Fresnel lens has a substrate carrier and refractive bodies arranged thereon. The substrate carrier underside can be arranged substantially parallel to the display and in particular be arranged directly on the display or even glued or otherwise connected with these, so that display and lens can form a solid unit. The substrate carrier may have the shape of a cylinder or prism, in particular that of a prism or cylinder stump with a beveled cut surface.
  • The refractive bodies may each have a refraction surface at which incident light is refracted. Because different refraction surfaces can have different angles with respect to the display, the focal lengths of the individual refractive bodies can be different, so that distortions can be compensated by a so-called focal length progression. It is advantageous if the magnification of the lens depends on its vertical height and thus is also dependent on the distance between the observer and the display. For example, areas of the display that are further away from the observer, can be displayed larger than other areas that are closer to the observer and thus in the lower part of the display, so that distortions due to the oblique view can be compensated or reduced.
  • The individual refractive bodies can be tilted independently of one another, thereby correcting the distorted representation of the display due to the oblique view. If the substrate carrier is designed as a prism or cylinder stump, in particular with a bevelled cut surface, the lower side of the substrate carrier and the upper side of the substrate carrier are not parallel to one another, so that all the refractive bodies arranged on the substrate carrier can be tilted by a common angle.
  • In addition, the refractive bodies can also be displaced by a certain proportion, so that the lens has a uniform thickness despite the tilting of the refraction bodies. This is particularly advantageous to minimize the thickness of the lens and the depth of the angle mirror. By tilting individual or even the entire refractive body distortions, in particular due to the oblique view, be compensated or reduced.
  • In one possible embodiment, the lens is arranged such that the display is arranged between the lens and the focal length of the lens. Preferably, the lens is arranged such that the display is arranged in the focal length of the lens or in the focal length of the individual refractive body. When the display is placed in the focal length of the lens, the display is displayed at infinity and can be viewed by the observer essentially without accommodation, so that the observer's eye, after looking at the vehicle surroundings via the angle mirror, is not much closer Must adjust the display. This offers the advantage of relaxed vision, regardless of what is to be observed and thus leads to a low eye strain.
  • It has also proven advantageous if the lens or the refractive bodies of the lens are tilted in such a way that the lens plane, in particular the central refraction body plane, the display plane and the observer plane intersect in a straight line. By means of this so-called Scheimpflug condition, both the display areas, which are closer to the observer due to the oblique view, and also the areas further away, can be sharply imaged, so that the depth uncertainty can be reduced.
  • The distance between the display and the lens is therefore decisive for the tilting of the lens, so that it is advantageous if the lens is arranged as close as possible to the display, so that the tilt and thus also the overall depth are as small as possible.
  • The substrate carrier of the lens may be wedge-shaped, so that the oblique side of the wedge is arranged parallel to the display and thus, for example, can rest on the entire surface thereof. Alternatively, the substrate carrier can also be straight and be attached to the display, for example, by means of an adhesive wedge.
  • The refractive power of the lens depends on the wavelength of the incoming light rays and thus on the color of the light. In order to avoid or reduce chromatic aberrations due to the resulting chromatic aberration, a color filter may additionally be arranged in the region of the lens, alternatively also only in the region of individual refractive bodies.
  • It has also proved to be advantageous if the display light path or the corresponding light beams of the display between the viewing opening and the lens and in particular between the display and the lens are free of prisms. In this context, the term "prism-free" is understood to mean that the light beams can be deflected to the observer without being deflected to prisms or mirrors or without being coupled out by devices such as beam splitters. The intensity of the light rays on the display and at the observation point can be almost the same.
  • Furthermore, it has been found to be advantageous if the ambient light path or the incident light rays from the environment are passed through the angle mirror as possible without being absorbed, and the tube or the light path between viewing and viewing section is accordingly free of absorption elements. This is particularly of great advantage if the environment is to be observed at night, since then only light rays with low intensity are incident on the angle mirror, which would lead to an additional absorption or back reflection of the light rays to the view is very much impaired.
  • It has also proven to be advantageous if the refractive bodies are arranged in a grid. The individual refractive bodies can be flexibly tilted independently of one another, so that the refractive characteristics of the lens are optimally adapted to the requirements can be. The orientation and / or position of the refractive bodies on the grid may be dependent on the location values of the lens. The refractive bodies may be twisted relative to the display, so that interference effects, such as the moiré effect, are reduced or avoided. The geometric dimensions of each refractive body may be selected such that interference effects can be reduced or compensated for. Each refractive body may have a different geometric shape.
  • Furthermore, the refractive bodies can be aligned in a symmetrical grid. For example, the symmetrical raster may be point symmetrical to the center of the lens. Alternatively, the grid can also be divided into rows and columns. All refractive bodies may have the same shape, for example may have the same dimensions. The refractive bodies can be aligned arbitrarily on the grid.
  • Furthermore, it has proved to be advantageous if the display is rotated relative to the lens or with respect to the refraction bodies. By twisting the display, interference effects, such as the moire effect, can be minimized or compensated. As a result, the image quality can be further improved.
  • In a particularly preferred development, distortions, for example due to the oblique view, can also be compensated by computation. The contents of the display are displayed in such a way that distortions are compensated.
  • Further details and advantages of the invention will be explained below with reference to an embodiment shown in FIGS. It shows:
    • 1 the angle mirror according to the invention in a side view,
    • 2 a detail of a side view of the angle mirror,
    • 3a d longitudinal sections through several Fresnel lenses,
    • 4 a plan view of a Fresnel lens.
  • In 1 the angle mirror according to the invention is shown schematically in a side view. An observer A is located inside a vehicle, not shown, for example, inside a wheeled or tracked vehicle, a ship, an aircraft or a submarine. The angle mirror 15 is arranged in such a way in the corresponding vehicle that light rays from the environment through a wall or through the armor of the vehicle can fall inside and there is no direct line of sight between the environment and the interior.
  • The angle mirror 15 has a view part 4 with a viewing opening 6 and a lookout section 5 with a lookout opening 7 on. Between view part 4 and lookout section 5 is a square tube 3 arranged in the form of a cuboid, with the viewing part 4 and the lookout section 5 connected is. The intro and outlook parts 4 . 5 have a triangular base and are designed as prisms.
  • Ambient light rays may be emitted from the environment 9 through the lookout 7 on the reflection surface 10 of the lookout section 5 fall where the ambient light beam 9 is reflected and through the tube 3 on the reflection surface 11 of the insight part 4 falls. There is the ambient light beam 9 reflected again and through the viewing opening 8th directed to the interior of the vehicle. The two reflection surfaces 10 . 11 are arranged parallel to each other, so that the ambient light beam 9 when crossing the lookout opening 7 and when crossing the viewing opening 6 runs parallel and thus there is a height offset of the incident light rays 9 comes.
  • the display 1 is at the side of the tube 3 arranged, that of the insight opening 6 faces. The display sends display beams 8th off, on the lens 2 or at the corresponding refraction bodies 13 the lens 2 to get broken. From the lens 2 fall the display beams 8th through the tube, where they enter and exit the tube 3 be broken again. The display beams 8th However, they are not deflected by mirrors, prisms or similar elements, or reflected, so that the display 1 can be observed directly. It is therefore a so-called direct-view display 1 ,
  • The display beams 8th and the ambient light rays 9 intersect behind the viewing opening 6 at the point S , At this point is the observer A or its eye. Because of the fact that the light rays 8th . 9 in one point S it will be the observer A allows, depending on its viewing angle, either the environment or the display 1 consider. This will be referred to below 2 explained in more detail.
  • The Observer A is located in a very short distance to the angle mirror 15 or to the viewing opening 6 , In addition, the entire angle is 15 designed such that it has the smallest possible depth. This is the display 1 so close to the viewer A that the display 1 only because of a large accommodation could be observed. To the distance between observers A and display 1 visually enlarge, so that a relaxed and largely accommodation-free vision is possible, has the lens 2 about refractive body 13 that the picture of the display 2 can map at infinity. It also comes from the fact that the display 1 not at eye level, but above it is arranged on the tube wall, on the one hand to distortions due to the oblique view and on the other hand also to impairments due to the refraction of light on the tube walls. The Lens 2 is suitably equipped so that these impairments are reduced or avoided. The structure of the lens 1 will be described below on the basis of 3a to 3d explained in more detail.
  • Even if the light rays 8th . 9 or the corresponding light paths are shown in the drawing only as thin lines, it is understood that these are only for a single representative light beam, but a total of significantly more light rays, for example, parallel to these, through the angle mirror 15 come in or from the display 1 to be sent out.
  • 2 also shows the in 1 illustrated angle mirror, wherein the observer plane B , the display level D and the lens plane L are shown. As already described, at a first viewing angle α 1 the vehicle surroundings and at a second viewing angle α 2 the display 1 to be viewed as. Because the display level D and the observer level B when viewing the display 1 Are not parallel to each other, it comes to an oblique view and thus to a distorted perception of the display 1 ,
  • Due to the second viewing angle α 2 it is capable of the lens 2 not, the entire display 1 Sharp, since different areas of the display 1 different distances to the observer A exhibit. Because of this, the lens must be 2 or the corresponding refractive body 13 be tilted so that the display level D , the lens plane L and the observer level B in a straight line G to cut. In the illustration in 2 stands the straight line G perpendicular to the figure plane, so that the straight line G there is only visible as a point. Since at oblique view the observer level B and the display level D are not parallel, the tilting of the lens must be 2 to the position of the display 1 or to the position of the display 1 and the observer A be adjusted. By appropriate tilting can thus the entire display 1 be shown sharp and there is no or only a slight blurring.
  • When considering the vehicle environment, the first viewing angle α 1 is about 90 degrees, the observer plane B is therefore perpendicular to the incident ambient light rays 9 , To see the display now 1 To observe must be the eye of the observer B be swiveled upwards. The angle required for this corresponds to the difference between the first viewing angle α 1 and the second viewing angle α 2 . After the eye has been swung up accordingly, the observer level is B again perpendicular to the incident light rays, in this case perpendicular to the display light rays 8th why in this position the display 1 can be observed.
  • In 3 are corresponding embodiments of the lens 2 shown. The Lens 2 is as a Fresnel lens 2 formed and has a substrate carrier 12 and refractive bodies disposed thereon 13 on. The substrate carrier 12 is on a display, not shown 1 arranged so that the display light beams 8th first from below onto the substrate carrier 12 and then on the refraction bodies 13 to meet. The refraction bodies 13 have one of the incident light beams 8th oblique refraction surface, at which the light rays 8th be broken or distracted accordingly.
  • Because of the refraction bodies 13 different angles to the substrate carrier base or to the display arranged thereon 1 may have, the lens 2 be made significantly thinner than lenses with only a single continuous refractive body.
  • To compensate for the distortions due to the oblique view, the refractive bodies, as in 3d shown to be tilted by a certain angle β. Alternatively, the substrate carrier may also be used 12 , as in 3c shown to have a beveled surface, all on the substrate support 12 arranged refractive body 13 be tilted by the same angle γ. In addition, the substrate carrier 12 also by means of an additional wedge 14 , For example in the form of adhesive of the substrate carrier 12 with the display 1 connects, be tilted, as in 3b is shown. These two tiltings can also be superimposed, so that the lens 2 best possible to the conditions in the angle mirror 15 can be adjusted.
  • Furthermore, the refractive bodies, as shown in FIG 3d is shown offset by a certain value perpendicular to the substrate support plane, so that due to the tilting and the displacement of the refractive body 13 altogether a lens 2 with a minimum thickness.
  • In the 4 is the Fresnel lens 2 shown in a plan view. The refraction bodies 13 the Fresnel lens 2 are aligned to a grid. The raster values i, j are dependent on the spatial values x, y of the Fresnel lens 2 , Because of that every refraction body 13 independent of the other refraction bodies 13 can have tilted or other geometric dimensions, the tilt and the geometry of the refractive body 13 as functions of the location values x, j of the Fresnel lens 2 being represented. In the 4 are just a few of the refraction bodies because of the better overview 13 designated.
