Panoramic aerial camera Multi-infinite target simulation device, it belongs to the camera performance testing system, an important part of the optical system is mainly composed of three resolution measurements with large field of view Apochromatic objective lens collimator structure, purpose is to simulate an infinite distant target to complete the aerial camera in the whole field of view scanning area, the static and dynamic camera resolution test, which is easy to verify that the camera has reached the design requirements.The article mainly describes the panoramic aerial camera completed the multi-infinite target simulation device testing, including the infinity focal plane target simulation device test technology research; three infinite target simulation device axis co-planarity test technical research; the angle between the system unit testing technology research; multi-target simulation device infinity axis intersection with the camera side mirror alignment material testing technology research. Test methods are given, and its detection calibration, the measured instrument focusing accuracy of less 0.05mm, 3 axis co-planar degrees 0.039mm, installation angle accuracy is up to 6 ’, apparatus, 3 axis precision alignment with the camera 30 ’. Meet the requirements to ensure the accuracy of the assembly.
