Paper Abstract

With the development of high performance focal plane arrays (FPAs) which provide very good sensitivity, operability, and excellent image quality, FPAs are applicable to wide-field-of-view, long range surveillance and targeting missions. However, many applications, like space- and air-borne surveillance telescopes, emphasize wide field of view (FOV) over resolution, permitted the most rapid survey of the entire field of regard. This is typically limited by large, complex, and costly corrector optics to flatten the wavefront. An alternative approach is to design a curved focal plane to alleviate the designing burden of optical system. Conventional approach is by the way of providing the ability to produce FPAs with a specified degree of curvature while preserving required electro-optical characteristics. After brief introduction normal FPAs based novel method in virtue of spot-to-curved-line converter, the paper presents the dynamic performance analysis of this Curved focal plane compensation imaging system in detail.
