Theoretical aspects of Fourier Transform Spectrometry and common path triangular interferometers.

摘要: Recent investigations have induced relevant advancements of imaging interferometry, which is becoming a viable option for Earth remote sensing. Various research programs chosen the Sagnac configuration new interferometers. Due to growing diffusion this technique, we developed self-contained theory describing signal produced by triangular FTSs and its optimal processing. We investigate disadvantages multiplexing, compare dispersive with FTS instruments. The paper addresses some methods correcting phase error, non-unitary transformation performed interferometer. effect noise on spectral estimations discussed.
