Design of an Interferometric Spectrometer for Environmental Surveillance

Abstract : This thesis describes the design of a field-portable spectrometer for spectral measurements in the visible and very near infrared from natural targets such as vegetation and the atmosphere. The instrument is a non-scanning version of the Fourier transform spectrometer (FTS) where the moving mirror is replaced by either a fixed, tilted mirror (holographic FTS, HFTS) or a fixed, Littrow-mounted grating (heterodyned holographic FTS, HHS, often referred to as spatially heterodyned spectrometer, SHS). This allows for a simpler and more rugged mechanical design than that of classical FTS instruments as well as a greatly reduced power consumption, all important advantages for a portable instrument for field use.
