Infrared spectral difference imager |
| abstract |
An infrared spectral difference imager capable of detecting and imaging an excess or deficit of infrared radiation having a preselected wavelength. The imager processes at least two channels of infrared radiation information through the sensor stage in order to display an image of the spectral differences present in the imager's field of view. The imager principles may be implemented in standard forward-looking infrared (FLIR) thermal imagers to obtain pictorial representations of the spatial distribution of sources and absorbers of infrared radiation within a preselected narrow band of infrared wavelengths. The spectral-difference detection capability may be added to scanning systems with discrete sensors, to scanning systems with TED or SPRITE sensors, and to staring array systems. Implementation techniques include a cost-effective manner of providing the time delays required to compare signals from the multiple energy channels and an automatic monitor and alarm system responsive to the strength of the difference signal. |
