Research of the Aerial Camera Lens to Eliminate the Secondary Spectrum

Abstract:

Aerial cameras are widely used in resource surveys, topographic mapping, military reconnaissance and many other fields. This paper introduced the sort of aerial camera, the development in our country and abroad about the theory of secondary spectrum. In order to meet the requirement for simple structure and high-resolution, the optical design of the apochromatism objective lens of aerial camera is achieved by common optical material. Objective’s focal length is 400mm, relative aperture is F/4 and work waveband is 420nm~850nm. Designing results show that the MTF of every field above 0.75 in 60lp/mm and satisfy the requirements of imaging for large frame array CCD whose effective size is 36mm×48mm.
