05373151 is referenced by 25 patents and cites 6 patents.

An imaging optical system is described including an array of photodetectors, each photodetector having a surface, and a focusing system for focusing a beam of electromagnetic infrared energy on the surface of at least one of the photodetectors. The focusing system further includes a technique for periodically defocusing the beam of electromagnetic infrared energy on the surface of at least one of the photodetectors. With such an arrangement, a scanning and focusing system is provided wherein fixed pattern noise can be decreased.
