Optical microsatellite visible light and infrared dual-band sub-pixel imaging device

The invention relates to the technical field of satellite payloads, in particular to a low-orbit earth remote sensing optical imaging device, and particularly relates to an optical microsatellite visible light and infrared dual-band sub-pixel imaging device. A linear array detector generally adopts a push-broom imaging mode; at the moment, the linear array detector realizes continuous sampling ofsatellite flight direction information by utilizing the movement of a satellite, and then a plurality of shot linear array images are combined into a complete image. Compared with scanning type imaging, the push-broom imaging system does not need a scanning mechanism, and the system structure is simpler. A high-resolution remote sensing image is obtained through a sub-pixel technology, so that thedevice is suitable for a resource-limited low-orbit earth optical remote sensing satellite. 本发明涉及卫星有效载荷技术领域，更具体地，涉及一种针对低轨道对地遥感光学成像装置，具体涉及一种光学微小卫星可见光与红外双波段亚像元成像装置。本发明线阵探测器通常采用推扫的成像模式，此时线阵探测器利用卫星自身的运动，实现对卫星飞行方向信息的连续采样，再将拍得的多幅线列
