Photoelectric equipment multi-optical-axis parallelism quantitative detection device

Abstract

The invention discloses a photoelectric equipment multi-optical-axis parallelism quantitative detection device. The device comprises an off-axis folded aspheric optical system, a CCD image sensor, a two-dimensional translation bench, a double-pentaprism expanding assembly and a control system. The off-axis folded aspheric optical system forms a collimation parallel light tube. The two-dimensional translation bench is installed behind a housing. A cross scale surface of the two-dimensional translation bench is superposed with a focal plane of the parallel light tube. A transition prism group is arranged below an aspheric secondary mirror to realize light parallel inversion. The lens of the CCD image sensor is aligned to the transition prism group. A support group is installed on the housing. Two ends of a beam expanding guide rod of the support group are respectively provided with a pentaprism, and the relative distance between the two pentaprisms is adjustable. The device is capable of realizing quantitative and precise parallelism measurement of every two laser/infrared/white light optical axes of multi-band photoelectric equipment, is advantageous by being wide in spectrum range, high in measurement precision, miniature and portable, and is applicable to optical axis parallelism testing among multi-band photoelectric equipment.
