Abstract

It is a hybrid design spectrometer with MWIR 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 analysis and data dimension reduction. The collimating light beam modulated by AOTF (acousto-optic tunable filter) provides a basis for the subsequent spectral analysis. The optical system realizes three times zoom from 160mm to 480mm. The simulation achieves the effect imaging result. Experiments show that the system has both imaging and spectral recognition capabilities.
