Design of a spectral zoom imaging system

It is a hybrid design spectrometer with zooming and spectral imaging. The system realizes the searching in large field of view and recognition in small field of view which can resolve the difficulty that the target and background of spectrometer are not easy to distinguish in a single field of view. It also decreases the difficulty of spectral demixing and data dimension reduction. The new lenses can simultaneously obtain optical imaging and spectral data which provides a basis for the subsequent spectral analysis. The optical system realizes three times zoom from 55mm to 165mm. The simulation achieves the effect imaging result. Experiments show that the system has both imaging and spectral recognition capabilities.
