Description
Cross reference to related applications
This application claims the U.S. Patent Application No. submitted on June 17th, 2015 priority of 14/742, No. 415, it is
All purposes is herein incorporated by quoting.
Technical field
The disclosure relates generally to the optical aiming device being used together with firearms.More specifically, this disclosure relates to
For the graticle used in dual focal plane optical aiming device.
Background technology
Graticle is aimed in optical aiming device and the distance or size of measurement object.Various types of graticles
It can be used in the optical aiming device of such as rifle scope.Wire cross-hair makes in graticle for many years
With.
Recently, glass etching graticle (glass etched reticle) is in consumer, army and law enforcement market
Catch in the middle Optical devices used.Glass etching graticle is one block of glass with the pattern etched into glass,
Then vapor deposition chamber is used, can be by various electrodeposition substances into etched pattern.For darkened features, usually using chromium.It is right
In " illuminating " feature, usually using titanium dioxide or sodium metasilicate.This fine powder is self-positioning in the future in graticle shell
Edge and user LED beyond the invisible light towards the eye reflections of user, and seen graduation plate pattern
To shine, thus in the case of low-light (level) it is easy to see that.
The optical aiming device of most of variable powers has two focal planes.In general, graticle can be placed in
One focal plane, the second focal plane or both place.Deposited for the first focal plane graticle and the second focal plane graticle
In clear advantage and shortcoming.
First focal plane graticle usually has less feature, this is usually because wire is too big and prevents from using metal
Silk.Therefore, glass etching graticle is normally used for the first focal plane graticle.Since the first focal plane is located at zoom amplification system
The front of system (that is, erecting system), so graticle and image mutually can proportionally change in size：When image becomes larger
When, the information on graticle becomes larger at the same rate.The advantage so done is, in any times magnification of user's selection
Under number setting, any measurement mark on graticle is all accurate.When image is exaggerated, information on graticle can be with
Image becomes larger at the same rate, therefore all graticles mark will all be accurate to the measurement scale of its design.However, one
The disadvantage is that, it will become thicker for the eyes of user due to forming the lines of graticle, because more visible areas
It is blocked, so seeing that small object may become difficult.If lines are too thin, (it is suitable for larger under low amplification factor
Visual field and mobile object) lines may be too thin and not see Chu.On the other hand, if lines are relatively thick and under low amplification factor
Work is good, then they can seem too thick under higher amplification factor.
In the second focal plane graticle, on the contrary, its advantage and disadvantage is generally opposite with the first focal plane graticle.Work as figure
When the amplification factor of picture is changed, because the second focal plane graticle is located at after erecting system, the second focal plane graticle is not
It is sized or ratio.Therefore, the second focal plane graticle is usually set according to the specific amplification factor of rifle scope to set
Size.In order to make the measurement mark on the second focal plane graticle accurate, it is necessary to be designed to be directed to given graticle accurate
Amplification factor is set to set gun sight.Therefore, in order to be indicated under another amplification factor using the measurement, user need with
Mathematical way calculating difference accurately uses.Since the rugosity of the lines on the second focal plane graticle is not set with amplification factor
And change, so lines can be optimized for desired rugosity, and under any amplification factor, lines are by user's
Identical rugosity is presented in eyes.
Some trend in current sighting device are worth noting.For example, there is increase amplification range in sighting device
Trend.The gun sight of amplification range with 6X is much, and some gun sights are even with the amplification in more than 10X
Scope.As amplification range increases, become the line roughness for being more difficult to the graticle that optimization uses in the first focal plane, because
For in amplification range the line size of graticle have too big change.Another trend is in long range situation and closely feelings
An optical aiming device is used under condition.Increased zooming range, which allows to have, can be used in very near and very remote feelings
One optical aiming device of condition.However, due to above advantages and shortcoming, it is difficult to find for long range situation and closely
Situation is all optimal graticle.
In the past few years, some optical aiming devices are used for dual focal plane graticle.This means the device
Include two graticles；There is a graticle in each in the first focal plane and the second focal plane.It is in general, most of double
Purpose (closely and remote application) graticle can have vertical stadia hairs and horizontal sight distance line, it, which has, specifies for long-range
The Hash-mark or some other shapes of the special angle measurement (for example, angle point or milliradian) of shooting.It is excellent for close range firing
Choosing uses simple point, the shape of a hoof, dotted line circle or some other marks.Current all dual focal plane optics known for inventor are taken aim at
Two graticles in standard apparatus are all glass etching graticles.
Reticule plate lighting has used many years in the rifle scope of traditional style, but there is also illumination to ask
Topic.The discussion of glass graduation plate technique will be useful background technology.Many years ago, glass graticle has been invented, because they have
There is the advantages of graduation plate features of realization " floating ".When applied to graticle, term " floating " means to set any
Meter is placed on the glass surface without any other physical support, that is to say, that the design is not required to be attached.Float
Graticle it is different from metal wire division plate because the latter requires all graduation plate features by being attached in some way to frame
Frame is supported, just as template (stencil) or neon light.Glass graticle causes any pattern being envisioned that becomes can
Energy.As described above, glass graticle manufacturer will use pattern etching glass, then according to different factors with a variety of materials
The region of material filling etching.In general, chromium is used as being filled in the non-material for illuminating the etched part used in feature.For shining
Bright feature, glass graticle manufacturer is usually using reflecting material, such as, but not limited to titanium dioxide and sodium metasilicate.In general,
In glass graticle, exist and be glued in graduation plate pattern to protect the second sheet glass of pattern, be consequently formed doublet.
However, most of glass illumination graticles are not bright enough to being enough to use in the case of bright daylight, because at present
Technology them cannot be made bright enough.This generality also has exception, but also has its shortcoming.Traditional reticule plate lighting is related to
Use the LED for being placed on glass graticle edge.Eye reflections of the light from LED from reflecting material to observer, so that
Pattern is illuminated in formation.This method is used to produce under low lighting conditions desired to illuminate pattern.But titanium dioxide and silicic acid
Sodium is actually the very thin abrasive flour of these materials.When the light from LED is irradiated on these materials, light meeting
To all directions scattering light.Some of which light passes to the eyes of user.But this is clearly poorly efficient, because it is by light
Scatter to all directions.The result is that the insufficient light reflected in the case of bright daylight.
A kind of alternative for providing more bright illumination is the light using the center that graticle is transmitted to by optical fiber come shape
Into bright central point or other shapes.For example, this is used in Vortex Razor 1-6x24 gun sights at present.Pass through light
The light of fibre transmission can be ambient light, or can also be provided by LED or other suitable light sources.Illuminating optical fiber with LED can produce
The very bright graticle that life can be seen under bright daylight, and when user removes on his head from axis not
Can be dimmed.The problem of this design, is that it can be used only on the second focal plane.Will the reason is that, being placed in the first focal plane
It is required that the shape illuminated is much smaller, correct size is presented to user, and it is difficult to make optical fiber sufficiently small, or at least make
Central point is so small.In addition, the use of optical fiber is difficult to accomplish using glass graduation plate technique without making observer see fiber optic cables
(which hinders the visual field and taking sb's mind off sth).Moreover, optical fiber is with only with the central point or herringbone that illuminate or other are similar
Small and compact form the shortcomings that.But without in the case of multiple optical fiber, the entity of disconnection is extremely difficult.Other illuminations
Type can produce the graduation plate pattern illuminated completely or the center pattern in addition to simple point.For example, using has quilt
The metal wire division plate for the optical fiber that LED illuminates.
It is diffraction grating graticle for making to illuminate another system that pattern becomes clear.Shi Hualuo generation is very in its Z6 series
Diffraction grating graticle is used in gun sight.This technology generates a very bright central point really.Problem be by
Light is supplied to the mode of diffraction pattern.U.S. Patent No. 7,804,643 B2 discloses a kind of prism system, it is by light reflection
To diffraction pattern to produce bright central point.The problem of this design, which is that it is depended on, to be needed to be placed on gun sight shell
Relatively large prism system on edge.It is this be arranged such that in the first focal plane set illuminate graticle be it is difficult,
Because larger shell arrangement may interfere with gun sight adjustment knob.Another problem of this design is, is adjusted adjusting
While whole button, graticle more moves on the first focal plane.Because prism, which plays, focuses light rays at diffraction pattern
Effect, therefore this design needs are absorbed in " mobile object ", it means that reflection light possibly can not be aimed at rightly all the time
Diffraction graduation plate pattern.Even if this prism apparatus can be caused to work on the first focal plane, still there will be in gun sight master
There is the problem of undesirable big shell on body.
Other people use diffraction grating graduation using the lens for combining very stringent tolerance in the first focal plane
Plate.This provides desired day brightness in the first focal plane, but when its head is moved away from axis by user, brightness is lost
Lose, and in some cases, which is darkened to almost black.
The alignment of dual focal plane graticle is also tool challenge.In many dual focal plane graticles, two graticles
Including vertical and/or horizontal graticule coverage stadia hairs or mark, include but not limited to " cross-hair " line.In addition, graduation
Other marks of plate also generally use, include but not limited to：Graticule coverage (subtension) mark, hash (hash) mark
Will, point, the shape of a hoof or other shapes or pattern.This mark can to shooter provide information, information include but not limited to measure away from
From, object size and how to compensate stop (holdover) and crosswind.Include line or mark on two graticles so that graduation
Plate is in alignment with each other of crucial importance.If causing graticle unjustified for any reason, user may can be appreciated that two groups of cross-hairs
With graticule coverage mark, this can perplex shooter and shooter is taken sb's mind off sth.This unjustified possible generation, because graduation
Plate physically without alignment or if user simply by its head off-axis.
Although the graticle of illumination is used for many years, they do not optimize also completely.For example, in the prior art
It is known to use transparent organic light emitting diode (OLED) screen or other electronic division plates, but this technology can be improved.Example
Such as, U.S. Patent Application Publication No. 2013/0033746 discloses transparent OLED screen curtain graticle and other kinds of electronics
Graticle, and the shape of various electronic division plates.However, a problem of the electronic division plate including OLED graticles exists
In if battery electric power loses, graticle is same.In this case, option is not aimed at.Another shortcoming be by
OLED screen curtain is connected to amplification factor may be very complicated.This difficulty causes the chance that more fails, and increases cost and answer
Polygamy.
Therefore, it is necessary to a kind of dual focal plane graticle, it is eliminated when the first focal plane graticle and the second focal plane graduation
Plate includes existing misalignment issues when cross-hair and other marks.Also need to that there is improved illumination and graticle option
Graticle.

Fig. 3 show in cross section the close-up illustration of optical system 14, it shows how light passes through optical system
14.Optical system 14 can have the additional optical of such as optical collector 22, and it is well known in the art that all
Some components such as objective system 16, erecting system 25 and eyepiece 18 can have multiple components or lens in itself.Shown here
Optical system 14 is plotted as the fundamental system for illustrating one embodiment of the present of invention, it should be appreciated that, have more
Or the modification of other optical systems of less structural element is also within the scope of the invention.
Fig. 4 is the basic of one embodiment of the dual focal plane optical aiming device 10 with objective end 40 and eyepiece end 50
The schematic diagram of component.The focal plane of neighbouring objective end 40 is the first focal plane 20 (FFP).The focal plane at closer eyepiece end is
Two focal planes 30 (SFP).Light enters objective end 40 and continues across dual focal plane optical aiming device 10 and pass through eyepiece end
50.When light passes through dual focal plane optical aiming device 10, light is focused with the first focal plane 20 and the second focal plane
Clearly image is formed for the eyes of user at 30.In the erecting system between the first focal plane and the second focal plane
Amplify in 25.Fig. 4 also shows optional Parts Controller 82 and switch 84.Controller 82, which can include, has memory
Chip, for storing various the graduation plate patterns or other information that are used by device.
In one embodiment of dual focal plane optical aiming device 10, (such as glass etching graduation of glass graticle 60
Plate) it is positioned at the first focal plane 20, and electronic division plate 70 (such as OLED graticles) is positioned in the second focal plane
In 30.For example, the pattern on glass graticle 60 can be the cross-hair for having Hash-mark, and electronic division plate 70
Pattern can be point as shown in Figure 6.It should be appreciated that can also use many other types and shape graticle and
Graduation plate pattern.
In an alternative embodiment, electronic division plate 70 is placed on the focal plane identical with glass graticle 60.
In another alternate embodiment, electronic division plate 70 can be positioned at the first focal plane 20, and glass graticle 60 is pacified
Put at the second focal plane 30.In a further embodiment, metal wire division plate can be used in any focal plane position.
On any dual focal plane optical aiming device, two graticles must rightly align, so as to when user is from mesh
When mirror watches two graticles, graticle seems to align as illustrated in fig. 8.If without rightly aliging, for user
Eyes for, graticle may seem unjustified as illustrated in fig. 5.If the first focal plane graticle and second Jiao are flat
Alignment between the graticle of face deviate from only one millimeter of sub-fraction, then for user will be obviously.When
When two graticles are rightly alignd, it is referred to as " true place ".
In dual focal plane optical aiming device 10, the first focal plane 20 and the second focal plane 30 may be quite remote from obtaining,
And graticle is physically fairly small (although they may seem very big by eyepiece) in itself.For example, glass etching point
Draw plate and be typically about 10 microns, and some graticles have the line of 0.005mm rugosity.As another example, the first focal plane
The distance of 50-100mm can be spaced apart in the main body of sighting device with the second focal plane.Therefore, it is difficult apart from upper at this
It is precisely aligned.The alignment of this small graticle needs very small movement.If dual focal plane optical aiming device has
Two glass etching graticles, then must mechanically carry out snapping to pinpoint accuracy, this be difficult complete and it is of a high price.Alternatively,
If dual focal plane optical aiming device has two electronic division plates, power failure causes do not have graticle at all.Therefore,
Have the advantages that in dual focal plane optical aiming device 10 one of a glass graticle 60 and an electronic division plate 70
In the complexity and cost that simplify two graticles that mechanically align.According to used manufacturing process, needs can be passed through
It is less or simplify double graticles alignment even without mechanical alignment.For example, electronic division plate 70 can use computer
Change or automation process digitally aligns with glass etching graticle 60.Some OLED screen curtain graticles have less than 5 microns
Pixel.Since this is about the half of the line width of glass graticle, it is easier to the digital graticle of alignment.In addition, if
Power failure occurs for optical aiming device, then glass graticle will keep visible and be acted as the spare solution that aims at
With.
Dual focal plane optical aiming device 10 can also have such as memory chip or inter-process in controller 82
Device, it includes various electronic division plate options, the point in such as Fig. 6, dotted line circle or the shape of a hoof in Fig. 5.Further, it is possible to use
The user interface of such as screen or dial switches between various graticle options.Once dual focal plane optical laying
Two graticles in device 10 are digitally alignd, then electronic division plate option can be optimized to and glass graticle 60
Work together and to provide a user many graticle options for selection.
In certain embodiments, optical aiming device 10 can also be for that can accommodate supersonic speed bullet and subsonic speed bullet
Firearms are particularly useful.For example, 300 grades of power-off (blackout) bullets are a kind of bullets that can be used in any way, still
In other rifles, different bullets can be used for every kind of function.Supersonic speed faster, and carries more energy.It is sub-
Velocity of sound is quieter, when being particularly used cooperatively with the silencer on rifle or noise silencer.Some shooters (such as penetrate by special operations
Hand) like there are two kinds of options, and like the type of bullet being used interchangeably according to task.
The optical aiming device 10 of the disclosure is adapted to this interchangeability.In one embodiment, optical aiming device
10 are suitable for being used together with subsonic speed bullet with supersonic speed bullet.Optical aiming device 10 can include controller 82, it includes
For the memory chip or internal processor for causing at least two indicia patterns to be shown on electronic division plate, the first pattern 75
Illustrate for the stop (hold over) being used together with supersonic speed bullet or angle index, and the second pattern 80 illustrates
Go out the stop for being used together with subsonic speed bullet or angle index, the second pattern has compared to the first pattern between mark
There is the interval of bigger.
In addition, when glass graticle 60 be in some Hash-marks the second focal plane in and electronic division plate 70
When in the first focal plane, the switch 84 on rifle scope is based on used bullet (subsonic speed is to supersonic speed) and changes one
Serial drop point or other " stop " aiming point or angle index.According to have selected supersonic speed or subsonic speed, can use
Different color, shape or any combination thereof distinguished between dwell characteristics.The implementation illustrated in figures 7 and 8
In example, the switch 84 on the side of press device 10 changes a little between supersonic speed pattern (Fig. 7) and subsonic speed pattern (Fig. 8).
Supersonic speed pattern and subsonic speed pattern can also be illuminated with different colors, to further discriminate between them.Color and/or shape
Any combinations can be used to be indicated between supersonic speed and subsonic speed.Since subsonic speed is slower bullet,
The bullet drop distance of bigger is can be appreciated that in set a distance compared to supersonic speed bullet.As a result, as shown in comparing Fig. 7 and Fig. 8
Go out, dwell point needs more to be spaced apart to adapt to this greater amount of bullet drop distance.Equally, Fig. 7 and Fig. 8
In one of the second focal plane graticle with glass etching mark that illustrates be, in battery electric power failure (simultaneously
Therefore the first focal plane graticle illuminate it is a little unavailable) in the case of), shooter still with the second focal plane graticle for
The benefit of reference.
In any embodiment disclosed herein, if battery electric power fails, glass etching or non-electronic graticle also may be used
The angle mark (MOA or MRAD) on basis is hashed to use, its midpoint corresponds to crosswind speed.
Alignment problem indicated above can pass through the element of the graticle in the first focal plane of separation and the second focal plane
And it is superimposed these yuan usually to solve so that the graticle mark in graticle mark and the second focal plane in the first focal plane
It is complementary.One example of this alignment problem is shown in Fig. 9 into Figure 11, is shown by including the first focal plane graduation
The view of the optical aiming device 10 of 100 and second focal plane graticle 200 of plate.As shown in Figure 9, the first focal plane graticle
100 (Fig. 9 A) are arranged at the first focal plane 20, and the second focal plane graticle 200 (Fig. 9 B) is arranged on the second focal plane 30
Place.First focal plane graticle 100 includes the vertical 102 and first focal plane horizontal sight distance line 104 of stadia hairs in the first focal plane.The
Two focal plane graticles 200 include the vertical 202 and second focal plane horizontal sight distance line 204 of stadia hairs in the second focal plane.Fig. 9 C show
Source is in the optical aiming device 10 of contracted position, and graticle 100,200 is perfectly aligned.In an illustrated embodiment,
One focal plane graticle 100 further include multiple graticule coverage marks 106 and reference numeral 108 along stadia hairs 102,
104 distributions.
When graticle 100,200 is perfectly aligned, the first focal plane stadia hairs 102,104 and the second focal plane stadia hairs
202nd, 204 undistinguishable.However, if graticle 100,200 is unjustified due to any reason, including when user simply will
When its sight removes perfectly aligned with the central axis 150 (referring to Fig. 1 and Fig. 2) of optical aiming device 10, presented to user
The view similar to the view in Figure 10, Figure 10, which shows to separate with the second focal plane stadia hairs 202,204, turns up the soil visible
One focal plane stadia hairs 102,104.It is especially chaotic for a user similar to the view of the view in Figure 10, because all
Line is all identical rugosity, and not it is apparent which stadia hairs belongs to which graticle.When optical aiming device 10
As shown in figure 11 during amplification, the first focal plane stadia hairs 102,104, graticule coverage line 106, numeral 108 and any other
