Divided-aperture infra-red spectral imaging system for chemical detection |
摘要 |
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. |

1. An infrared (IR) imaging system for determining a concentration of a target species in an object, the imaging system comprising:
an optical system including an optical focal plane array (FPA) unit, the optical system comprising a plurality of optical channels defined by components of the optical system that are arranged in a two-dimensional array, said plurality of optical channels being spatially and spectrally different from one another and configured to direct IR radiation from the object towards the optical FPA unit; a first movable shutter configured to be removably positioned to block IR radiation incident onto the optical system from the object, wherein a portion of the movable shutter is maintained at a first temperature and another portion of the movable shutter is maintained at a second temperature; and a processor configured to acquire multispectral optical data representing said target species from the received IR radiation in a single occurrence of data acquisition. |
