Abstract

Cooled infrared focal plane array (Cooled IRFPA) has been applied widely in military and civil fields. In the cooled focal plane array detector infrared imaging systems, narcissus as a unique defect has a degenerate effect on the image quality of cooled infrared imaging systems, such as blocky, annular or "corner heat" fixed pattern noise in infrared images. Therefore, the correction of narcissus effect using image processing method is important to infrared imaging systems. Through analyzing manifestation of narcissus effect by statistical approach, a cooled infrared imaging system model considering narcissus effect is established, by which a self-adaptive narcissus correction algorithm based on scene statistic and radial compute is presented. From the simulation and the experiment on an actual cooled IRFPA module, this algorithm is proved very effective on correcting narcissus effect and improving image quality. Moreover, the peak signal to noise ratio (PSNR) also increases obviously.
