Polarimetric Hyperspectral Imaging With Acousto-Optic Tunable Filter In The Visible To Shortwave Infrared Range

We developed polarimetric hyperspectral imaging instruments covering visible to NIR, and SWIR spectral ranges. The instruments are based on acousto-optic tunable filter and liquid crystal variable retarders, allowing full Stokes vector measurement with fast and full electronic tuning, with the acousto-optic device function both as spectral filter and analyzer. The instrument can find applications such as biomedical diagnostics, target detection, surveillance, atmospheric aerosol monitoring, metrology, and chiral molecules measurements.
