Paper Abstract

Thermal vision system with 2D sensor such as PtSi, InSb, MCT and any others in the commercial market is generally required to correct non-uniformity of response of every pixels in order to display satisfactory IR images. We have studied the non-uniformity correction methods for our thermal vision systems and in a previous study we proposed the most suitable non-uniformity correction method for PtSi SBD sensor. This method was optimized at a certain operating temperature, which was a room temperature. However thermal vision systems could be used at a various operating temperature. It is also obvious that his change of operating temperature causes input IR flux change to a sensor, this affects the accuracy of the measured results. Therefore, it is necessary not only to correct non-uniformity of each pixel but also to compensate this influence by the change of temperature to have a satisfactory IR image. In this paper, this compensation method is described. Besides, the result of this method is presented.
