The utlity model has following beneficial effect.
The utility model adopts the rhombic prism imaging characteristics, when the aiming light path of range finder using laser is passed through first 45 degree reflecting surface of rhombic prism, generation 90 degree are refracted to another 45 degree reflecting surface and produce 90 degree refractions again, light path parallel before light path after the refraction and the refraction, just be equivalent to the optical axis direction emitting antenna window of phantom-target antenna window is moved, aiming optical axis after the movement keeps the space parallel invariant position with mobile preceding former aiming optical axis, so not only dwindle interval between three, and guaranteed the reception optical axis of principle of work shown in Figure 5, launch optical axis and aiming optical axis, three collimation is with mobile preceding in full accord.Rhombic prism is reduced into d` with the spacing of launching optical axis from d with the aiming optical axis of the optical axis system of original range finder using laser, makes the clear aperture D of used catoptron
0` becomes 1.3 d`, has dwindled the clear aperture of used catoptron greatly, has alleviated weight, is easy to carry and installs.Aiming optical axis after the movement and mobile preceding aiming optical axis parallel fully (optical axis is constant), the deviation of the putting position of rhombic prism can not produce as inclination and picture simultaneously, can not cause the characteristic of optical axis imbalance, can guarantee range finder using laser optical axis adjustment accuracy, be suitable for the field work environment, convenient debugging.
Flexible for installation and cost is very low, dwindled in light weight being easy to carry of back mirror of logical light mouth, no longer be subjected to the restriction of field environment condition during use, the utility model adopts with the laboratory and detects the same detection principle of optical axis, by adopting rhombic prism to shorten the spacing of range finder using laser emission optical axis and aiming optical axis, dwindled the clear aperture of the needed catoptron of debugging range finder using laser optical axis widely, alleviated the volume and weight of catoptron, can carry also and use under the lowered in field environment.Can satisfy the index request of range finder using laser optical axis adjustment and the needs of battlefield maintenance, solved under the lowered in field environment situation, range finder using laser is carried out the adjustment of optical axis, and the optical axis adjustment error that causes of the foozle of rhombic prism is far smaller than the requirement of systematic optical axis collimation index, and manufacturing expense is low.
Simultaneously this equipment simple, be easy to carry and can satisfy and detect the adjustment accuracy requirement, originally the optical axis adjustment that can only carry out in the laboratory can be carried out under the environment in the battlefield, greatly reduce maintenance cost and servicing time, solved the problem that range finder using laser carries out maintenance and debugging under can not the lowered in field environment state.
The utility model can be applied to the optical axis check of multiple range finder using laser and proofread and correct, and solves under the situation in the open air the optical axis of range finder using laser to be proofreaied and correct and checked, and is easy to carry convenient the use and low price.Be applicable to the work of the small-bore catoptron accent axle that can not completely comprise emission coefficient, receiving system and three systematic optical axis of sighting system.
