Changchun Institute of Optics, Fine Mechanics and Physics,Chinese Academy of Sciences, Changchun 130033, China） infrared radiation; radiation characteristic measure; point target; radiation energy conservation 31-1577/TN Firstly,the basic principles infrared radiation characteristic measure was presented. Due to the diffraction effect of the optical system,point target＇s image is a dispersed spot. Point target radiation characteristic measurement accuracy is generally very low. Viewof this situation,one point target radiation characteristic measurement optimization algorithm based on radiation energy conservation was proposed,Specific principles and implementation process was given. Finally,point target radiation characteristic measurement experiment was done,and the results were analyzed. The results showthat the point target radiation measurement optimization algorithm ＇s accuracy i |
