A compact LWIR hyperspectral system employing a microbolometer array and a variable gap Fabry-Perot interferometer employed as a Fourier transform spectrometer

摘要

A prototype long wave infrared Fourier transform spectral imaging system using a wedged Fabry-Perot interferometerand a microbolometer array was designed and built. The instrument can be used at both short (cm) and long standoffranges (infinity focus). Si
