A New Infrared Sensor Model Based on Imaging System Test Parameter

This article presents an infrared sensor model based on test parameters. From standard geometrical planes infrared frames, some sensor parameters can be measured, such as SiTF, MTF, and noise. With the above parameters and some other characteristics, a sensor model is developed. The sensor model is validated through a point target test and a four-bar target test, and the error is below 5%.This model is unlike traditional models in that it does not need a series of parameters which a sensor user can not achieve, and it also has acceptable precision. This model shows a great convenience in scene simulation and scene analysis.
