Description
Technical field
The utility model relates to a kind of holographic optical elements (HOE), especially a kind of manufacturing installation that is used for the critical piece-laser hologram aiming optical element of laser hologram alignment clamp.
Background technology
The alignment clamp that adopts on the small arms has multiple.The prevailing iron sight that is the accurate heart to breach, this gunsight is firm in structure, low price, but it can only use simple eye aiming, and pointing velocity is slow and precision is low.When target or firearms this when mobile or ambient light when too dark, human eye just is difficult to aiming.Also having a kind of common gunsight is telescopic sight, and its principal feature is that pointing accuracy is higher, but is fit to the aiming to remote static target, is not suitable for the target of fast moving is closely aimed at.Also have two kinds of optical foresights: red-point aiming device and laser guide alignment clamp.The pointolite collimation that the red-point aiming device sends light emitting diode (LED), and with half anti-mirror with the collimated light partial reflection to human eye, be reflected to and aim on the object.This alignment clamp pointing velocity is slow, and owing to the part light direct beam human eye from the LED emission, the people is felt under the weather; In addition,, the brightness of run-home is weakened greatly, be unfavorable for effective aiming because human eye must see through half anti-sem observation.The laser guide alignment clamp is directly to be mapped in the run-home behind the optical alignment that a laser diode (LD) is sent, and its major defect is: (1) laser can be found by the enemy, is unfavorable for that the ejaculator is hidden; (2) if having a plurality of ejaculators aim at simultaneously very close to the enemy personnel, then might be hard to tell which laser spots and be the rifle of oneself and send; (3) far reach background light when strong when distance, be difficult to see laser spots by the object scattering.
Summary of the invention
The purpose of this utility model is to provide a kind of device of making the laser hologram aiming optical element with laser holography.
The utility model is provided with
1) device of 1 cross hair pattern-information of the 1st exposure record is provided with laser instrument; 1 spectroscope is positioned at light beam delivery outlet the place ahead of laser instrument, is used for laser is divided into direct beam and folded light beam; 2 catoptrons are located at respectively on the light path of spectroscopical direct beam and folded light beam; 2 are expanded the bundle wave filters, are located at respectively on the light path of folded light beam of 2 catoptrons, form reference light and thing light respectively; Frosted glass is located at the expansion bundle wave filter the place ahead on the return laser beam; The slide that has the cross hair pattern is close to the back side of frosted glass; The holographic recording dry plate is located at the intersection of reference light and thing light.
2) the 2nd exposure pen recorder is provided with laser instrument; 1 spectroscope is positioned at light beam delivery outlet the place ahead of laser instrument, is used for laser is divided into direct beam and folded light beam; 2 catoptrons are located at respectively on the light path of spectroscopical direct beam and folded light beam; 2 are expanded the bundle wave filters, are located at respectively on the light path of folded light beam of 2 catoptrons, form reference light and thing light respectively; Collimation lens is located at the expansion bundle wave filter the place ahead on the return laser beam, is used to produce parallel light; The holographic recording dry plate of 1 cross hair pattern-information device of the 1st exposure record places the intersection of reference light and thing light.
The optical devices of re-expose are difference to some extent on the thing light path only.
The said laser hologram aiming optical element of the utility model is a holographic optical elements (HOE), can produce the micro bright point of an in-plant cross hair image and remote (infinite distance in theory) under the irradiation of laser diode.Eyes see through the laser hologram aiming optical element during aiming, observe cross hair image center, bright spot and are taken aim at the object sight alignment, can reach accurate aligning.Be characterized in: cross hair image and micro bright point that (1) laser hologram aiming optical element is presented are the virtual images, can see just when having only this element of eye alignment that others can't see.If, good disguise is arranged so, compare with other optical foresight (as the laser guide alignment clamp) as the gunsight of weapon.(2) the empty bright spot that presented of laser hologram aiming optical element looks like to drop on by in the run-home, and distance is very long between bright spot picture and the cross hair picture, so compared with the method for sight of traditional accurate heart to breach, the pointing accuracy of hologram aiming optical element is very high.Need not shut an eye when (3) aiming at, do wartime, very big field angle is arranged, can observe enemy personnel's situation of movement better so be used for the battlefield.(4), therefore under relatively poor weather conditions or darker environment, still can aim at rapidly because eyes observe when aiming is distinct image and bright spot.
Description of drawings
Fig. 1 is the device synoptic diagram of 1 cross hair pattern-information of the 1st exposure record.
Fig. 2 is the synoptic diagram of the 2nd exposure pen recorder.
Embodiment
As Fig. 1, shown in 2, the utility model adopts the method for a holographic recording dry plate re-expose is made the laser hologram aiming optical element.The information of a cross hair pattern of the 1st exposure record, the information of an infinite distance micro bright point of the 2nd exposure record.The optical devices of re-expose are only in thing light path difference to some extent.No. the 1st pen recorder is provided with laser instrument 31, spectroscope 32, catoptron 33 and 34, expands the slide 39 of restrainting wave filter 35 and 36, holographic recording dry plate 37, frosted glass 38 and having the cross hair pattern as shown in Figure 1.Frosted glass 38 is close together with the slide 39 that has the cross hair pattern, with the distance of holographic recording dry plate 37 be good with several centimetres.Reference light is with expanding Shu Guang, and the distance that expands bundle wave filter 36 and holographic recording dry plate 37 should be the same with the distance of the relative laser diode of laser hologram aiming optical element in the application, just can make the cross hair image of reproduction that sharpness is preferably arranged.The light that is radiated on the frosted glass 38 also can be directional light, reaches the purpose of record cross hair pattern equally.
No. the 2nd pen recorder as shown in Figure 2.The different only a branch of directional lights of thing that only are of this device and Fig. 1, its generation are directly to be mapped on the holographic recording dry plate 37 after will expanding the expansion bundle optical alignment of bundle wave filter 35 generations with collimation lens 40.The purpose of this arrangement is to produce the pointolite of an infinite distance as thing.Other mark in Fig. 2 is identical with Fig. 1.
Do not change reference light, not mobile holographic recording dry plate in the record of the 1st time and the 2nd time.The thing light path should be on same straight line to the central point of each parts the holographic recording dry plate 37 from expanding bundle wave filter 35 in the secondary pen recorder.
After two steps, record was finished, the holographic recording dry plate is carried out common chemical treatment, promptly make the laser hologram aiming optical element.When laser diode being placed on the local of reference light same distance and during with this element of identical angular illumination, can be observed the virtual image of the bright spot of in-plant cross hair pattern and infinite distance.
