Design and Verification of Pointing Dual-channel Satellite Remote Sensing Camera
A design for a pointing dual-channel satellite remote sensing camera is presented.The multi-spectral imaging function,providing a viewing range of over 1000 kilometers,is achieved by combining a large-range pointing mirror and a dual-channel focal plane module.The pointing mirror is characterized with a large-aperture and super lightweight design,ensuring good imaging stability and mechanical properties.The pointing mechanism incorporates a high-precision driving unit and a precision angle-measuring device to ensure precise visual axis pointing during large-scale rotation.The focal-plane component is designed with a double-channel wedge lens splitting,enabling high-precision matching of nine spectral bands and ensuring the quality of camera image fusion.The high stability of the camera is realized through the design of the opto-mechanical structure.Environmental tests demonstrate that the camera exhibits high pointing accuracy,ex-cellent stability and environmental adaptability.
