Dual-band infrared optical imaging system design by wavefront coding

Abstract

The revolution in dual-band infrared focal plane arrays over the past ten years has induced a significant impact on dual-band imaging system design. There are numerous challenges facing dual-band imaging system design using traditional methods. In this paper, Wavefront Coding technique is used to offer the potential implementation of infrared dual-band achromatic and diffraction-limited imaging by using simple optics. An example in terms of a one-element dual-band infrared imager is given.
