The push-broom camera with a resolution of 0.5m can obtain static push-broom images with a resolution of 0.5m and a swath width of more than 15km. It has the characteristics of high resolution, high integration, and intelligence, and the research and development period is one year.
The push-broom camera with a resolution of 0.75m adopts the coaxial folding optical system,and can obtain high-resolution images with a resolution of 0.75m in 535km orbit.It has experience in orbital operation.
The multispectral camera with a resolution of 5m has 19 spectral bands, adopts cook-type f-axis triple reflection optical system, and has the advantages of high transfer function, multi-spectral bands and high signal-to-noise ratio, etc. The camera has the functions of on-orbit focusing and radiation calibration. It has experience in orbital operation.
The micro-nano camera with a resolution of 2m is one of the core components of Earth observation satellites, which can be used for CubeSat, and has the advantages of small size, light weight and high resolution.
The camera's optical system of the fundus imager consists of an illumination system and an imaging system. The illumination system is equipped with a fixation light source, visible illumination light source, and near-infrared focusing light source. Focusing with near-infrared light sources can be performed without pharmacologically dilating the eye. The imaging system is equipped with a focusing lens and provides a refractive compensation function of±20D.
