Abstract

A dual-channel focal plane with optical mechanical and electro thermal highly integrated designing is proposed. Firstly a light splitter is applied in the light path, which split the effective light to two focal plane channels with different field of view. To ensure the focusing consistence of these two focal planes, the team splitter is loaded on focusing mechanism, which changed the focusing location of the light, thus the dual-channel focal planes could be focused. The two focal planes have different detectors which give different spectral bands. There are nine detecting spectral bands in all, which is double of the single-channel focal plane camera. With dual channel, multispectral detecting is realized. The spectral range is from visible to near-infrared. This dual-channel focal plane camera is on orbit for more than one year, and it gives fine photos.
