Abstract

With the development of space remote sensors, the urgent needs of large area array optical detectors increase strongly. To address the conflict between the resolution and the detector size, the most straightforward approach is to use a larger CCD chip, but a single small area array CCD chip cannot meet the needs of the focal plane, therefore, the method of CCD mosaic must be used. This paper presents a new method of splicing, it's a twice-imaging scheme. The first image is formed on an imaging plate of intercepting optical component, and then four separate CCD cameras are used to produce the segmented images on the final image plane. So a CCD focal plane mosaic can be achieved.
