Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a digital zoom spectral imager based on a microlens array sensor. Background technique [0002] The spectral imaging system can acquire the image and spectral information of the target at the same time. It is an optical sensor with "complete performance" and integrated map and spectrum. The current spectral imager can already realize multiple adjustable bands, strong spectral resolution and high spatial resolution. Advantages, it is suitable for airborne and spaceborne remote sensing fields such as staring imaging, and provides relevant departments with new technical means for mineral resource exploration, biomedical diagnosis, and agricultural pest monitoring. However, in actual remote sensing applications, due to the uneven distribution of remote sensing objects, in order to obtain clear remote sensing images, it is necessary to perform zoom control according to the te...
