Abstract
A multiband IR adjunct (MIRA) sensor to spectroscopically determine the content and the concentration of chemical composition of a targeted object, includes a sensor housing, a first front optics in a first optical channel, a second front optics in the first optical channel, an acousto-optic tunable filter (AOTF), a photo detector (PD), a set of back optics in the first optical channel that focuses polarized narrow-band light beams received from the AOTF device onto the PD, the PD converting the polarized narrow-band light beams into an electrical signal, and a data acquisition unit signal-connected to the PD, the data acquisition unit collecting the electrical signals. Multiple optical channels can be provided within the housing to analyze UV/VIS/near infrared (NIR), short-wavelength infrared (SWIR), mid-wavelength infrared (MWIR), and LWIR wavelength ranges respectively.
