Abstract
Cooled infrared detectors are often subject to Narcissus effect. Article describes an algorithmic approach to its correction for an optical system with variable focus length for different focusing distances. It is based on interpolating of a small number of base correcting frames. Procedures of interpolation for the case of changing only focus length or only focusing distance are described. Procedure for the case of changing the both parameters simultaneously is also presented. Requirements for base set of correcting frames are described. An example of algorithm application is also presented.
