Study on an Infrared Detector Parameter Measuring System

This work introduces a novel parameter measurement model for an infrared detector. Firstly, the models for calculating the parameters of an infrared detector are studied and established, such as hysteresis, repeatability, and sensitivity. Then, experiments are implemented to validate and analyze the aforementioned parameters, demonstrating the accuracy and validity of the parameter computation model. This research has guiding significance for the accurate measurement of the index parameters of infrared detectors, and it is also helpful for the calibration method, error analysis and correction of infrared detectors.
