Abstract

The invention belongs to the technical field of photoelectricity testing, and relates to an infinite and finite conjugated differential detection focusing photoelectric image analyzer which integrates light, machine, electricity, arithmetics and automatic control and a realizing method thereof. According to the invention, clear acquisition and focus fixing of a reflection light path target image are realized through high precision differential confocal focusing of a transmission light path; finite conjugated optical system parameters are tested by adding an optical-electric image analyzer measurement objective lens; through translation and rotation of the photoelectric image analyzer, optical parameters of optical system axis and out-of-axis fields and a folding axis system are measured; and finally high-precision comprehensive test of axis and out-of-axis field optical parameters of an infinite and finite conjugated target optical imaging system is realized. The infinite and finite conjugated differential detection focusing photoelectric image analyzer can precisely, rapidly and automatically collect, analyze and process images of the optical system through a corresponding measurement method and software control, so as to acquire performance parameters of an infinite and finite conjugate photoelectricity instrument.
