Abstract
A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.
Claims18
An infrared (IR) imaging system comprising:
- a plurality of reimagining lenses;
- a plurality of front objective lenses positioned to collect an IR radiation from an object and relay the IR radiation to the plurality of reimaging lenses through a plurality of field references and a plurality of relay lens array;
- a plurality of spectrally multiplexed optical filters;
- and
- a plurality of spatially and spectrally different optical channels positioned to transfer the IR radiation from the object towards an optical focal plane array (FPA) unit through the plurality of spectrally multiplexed optical filters;
- wherein each of the plurality of reimaging lenses is positioned to transmit the IR radiation that has traversed one of the plurality of spectrally multiplexed optical filters towards the optical FPA unit.
