2) the 2nd exposure tape deck 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 speculums 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 speculums, 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 utility model can be applicable to the laser hologram sight, the laser hologram sight is provided with laser hologram aiming optical element, laser hologram aiming optical element seat, laser diode and power supply, the laser hologram aiming optical element is located on the laser hologram aiming optical element seat, laser diode is located at the place ahead of laser hologram aiming optical element and is electrically connected with power supply, and laser hologram aiming optical element seat, laser diode and power supply are located on the weapon.
Said laser hologram aiming optical element seat is preferably the holder of strap clamp, is convenient to be clipped on the used weapon, for example on the gun barrel.When installing and using, the position between reply laser hologram aiming optical element, laser hologram aiming optical element seat and the laser diode adjusts accordingly.
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 (infinity 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 sight) 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 laser hologram aiming optical element is very high.Need not shut an eye when (3) aiming at, do wartime, the very big angle of visual field 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.
