Abstract:

A data collection sensor based on a Bomem Fourier transform spectrometer was used to measure infrared multispectral targetbackground signatures. This report describes the data collection sensor, including data processing software for quick look data analysis, gives the sensor characteristics test procedures and their results, and analyzes the effect of the sensor characteristics on the quality of the measured signatures.The sensor gives a very high level of performance including noise equivalent spectral radiances of 1 nWsq cm sr cm-1 in the MWIR 3 to 5 micrometers region and 6 nWsq cm sr cm-1 in the LWIR 8 to 12 micrometers region, a relative calibration accuracy to less than 0.25 above 4 micrometers, and spectral band-to-band correlation preservation greater than 0.9999 in the LWIR, and greater than 0.9995 between MWIR and LwIR and within the 4 to 5 micrometers region of the MWIR.
