Abstract

The invention is an optical system for up-conversion of SWIR images into visible images. The optical system of the invention comprises a liquid crystal optically addressed spatial light modulator (LC-OASLM), which acts as an optical valve, and two optionally GRADIUM lenses to reduce the size and complexity of the optical setup. In embodiments of the invention, the photosensitive layer is replaced by a photodiode or array of photodiodes and the liquid crystal layer is replaced by an array (film) of organic light emitting diodes which emit light at the VIS by collecting SWIR light or by a fluorescence layer with sensitivity in the SWIR range.
