Portable type external field equipment for multi-sensor optical axis calibration

Abstract

The invention discloses potable type external field equipment for multi-sensor optical axis calibration, comprising an adjusting optical axis mechanism, an optical collimation assembly and a rotary target wheel assembly, wherein the adjusting optical axis mechanism is located on sensors with different wave sections; the optical collimation assembly is provided with a front window and a back window; light which is input from any one window of the optical collimation assembly is reflected twice and then is output from the other window; the sensors at the different wave sections are located outside the front window of the optical collimation assembly and parallel light is received or sent by the optical collimation assembly; the optical collimation assembly is in butt joint with the rotary target wheel assembly through a connecting component at the back window side of the optical collimation assembly; and the light is input to the back window of the optical collimation assembly through rotating to select different target positions on the rotary target wheel assembly. The potable type external field equipment disclosed by the invention can work in a wide spectral region and the requirements of carrying out optical axis debugging and calibration on the sensors with the different wave sections in an external field environment are met.

AI Technical Summary

Problems solved by technology

The existing multi-sensor optical axis calibration equipment covers a limited range of wavelengths, which cannot meet the current needs of optical axis calibration and testing of multi-sensor systems that work in a wide range of wavelengths (such as 400nm to 14μm); in addition, the existing optical axis testing equipment. It is bulky and has poor environmental applicability. It is only suitable for indoor use and cannot meet the needs of multi-sensor photoelectric system for optical axis adjustment in the field environment.
