Abstract
For outdoor infrared device, the calibration process establishes the relationship between input energy and output gray. This paper constructs the outdoor calibration system of infrared device, analyzes the energy transporting process of calibration by collimator, calibration by near blackbody, calibration by overlap blackbody, and demonstrates the process of calibration. By analyzing the physical meaning of calibration parameters, this paper points out the same aspects and different aspects of system response,based on which the method of computing luminance of aircraft is proposed. Also this paper proposes the method of measuring blackbody with middle range, which can be applied to validate the atmospheric transmittance and method of calibration.关键词
