Infrared Image Restoration Algorithm Based on Substrate-free Focal Plane Array
基于无基底焦平面阵列的红外图像复原算法

It is different from traditional substrate with focal plane array that thermal sensitive element of substrate-free focal plane array can absorb infrared radiation. The absorbed infrared radiation is conducted to adjacent cells in the form of a point spread function. Although this thermal characteristic can improve infrared detection performance greatly and can make the infrared target much more prominent against the background, but at the same time the thermal characteristic is able to reduce the infrared target detail distinguishing ability and result in image blurring. In this regard, through analyzing the thermal diffusion additive effect on infrared imaging quality, and using digital image processing method, a targeted image restoration algorithm is proposed in this paper to solve above problem. Both simulative and experimental results show that the image restoration algorithm can effectively enhance the detail contours of infrared image then highly improve image quality.
