The problems of the remote monitoring of the Earth surface, rational use of natural resources, observation of natural phenomena and ecological catastrophes' bring forward the issue of further upgrading and improvement of multispectral image devices. The current demand for multispectral data to be used in research and application fields is so great that existing systems often fail to provide adequate support This is primarily true for the quality and contents of image data. Nowadays accurate radiometric (absolute and relative) calibration, high - precision geometric survey and registration images of different spectral band , as well as high system efficiency are Critical requirements for any application. The optoelectromc OC-RSES-02 camera, which is currently under development,is the further development ofthe MultiSpectral Optoelectrothc Camera'. Both cameras use a multichannel single-chip CCD and operate in the visible, but the OC-RSES-02 is quite a new photodetector because it includes six identical CCD linear 1024 pixels arrays of 13x13 im photodiodes size. Generally, the increase of the focal length of the camera objective to 300 mm improves the resolution, though decreases the field ofvision. Another innovation that considerably improves the OC-RSES-02 performance as well as the value of the information is the availability of an 1.55-1.75 m IR chanel. The OC-RSES-02 camera can be installed on a spacecraft or aircraft. The information obtained can be recorded into an onboard computer and then processed either at ground stations or in a real-time mode on board an aircraft. The data obtained in all spectral bands can be used for thematic mapping of the Earth surface, studying dynamic surface phenomena etc. |
