Research on Measurement Method of Characteristics Infrared Small light Points Beam

摘要

The infrared small spot system is the main equipment to test the crosstalk of the infrared focal plane array device. According to the current test method can't meet the infrared light spot characteristics of the test problem, the use of infrared imaging device scanning technology to build a small infrared light beam characteristics of the calibration System, to achieve the infrared light spot characteristics of the measurement, and the system of the uncertainty was assessed. Finally, chooses an infrared small spot optical system is used to verify the measurement uncertainty of the system. It can be seen from the data analysis that the method can measure the characteristics of the infrared light beam and meet the measurement of the infrared small spot optical system. Infrared small spot system development and infrared focal plane crosstalk test to play a certain help.
