Abstract

Fourier transform spectrometers are considered, and emphasis is placed on resolution and the speed of data acquisition. Detector linearity requirements are discussed as well as trading the multiplex advantage for the throughput advantage. Radiometric accuracy is considered, and focus is placed on instrument design and operational parameter optimization. Issues of calibration are presented, and it is noted that using black bodies for calibration can saturate the detector with long-wavelength radiation, before sufficient signal-to-noise ratio for the short-wavelength radiation is reached. It is suggested to look for secondary calibration sources and to refrain from calibrating a narrow-band emission spectrum with a black-body radiator.
