Paper Abstract

With numerous hi-tech applications in photoelectric equipment, Single optical sensor has no capacity enough to shoulder those complex war-field tasks. Different photoelectric sensors have to cooperate effectively each other in order to exert effectively their own function. Therefore, how to test the multi-optical axis collimating aberration among each optical sensor is the fundamental precondition to guarantee the effective cooperation of each optical sensor. A new type automatic testing device is provided in the paper, which chooses the reflecting type parallel collimator as optical system. Design the paraboloidal lens as the primary mirror and the hyperboloidal lens as the secondary mirror not only guarantee the important index of resolving power but also shorten the length of collimator. Furthermore, design the laser spot collection set based on up-conversion effect of rare-earth material to satisfy the testing need between visible light axis and laser axis, which can capture effectively laser spot. Finally, design also a shift light set to meet the need of the practical distance between two axes of photoelectric equipment, which cover the shortage of the narrow caliber of parallel collimator. The merit of automatic testing device of multi-optical axis collimating aberration is prominent, such as excellent mobile capacity to meet the in-field condition, higher automatic degree to meet the different user and the broad applying field to meet different photoelectric equipment.
