In both Fourier Transform Spectroscopy and Time-Domain Spectroscopy in the THz frequency region, many of the measurements are performed on samples of a single material and given known thickness to either characterize a material sample, characterize a reference substrate of material for a subsequent measurement, or where superior data on that sample exists, calibrate the system accurately. In this...
Spectral-spatial interferometry pioneered in a narrow band in the near infrared has not enjoyed much exploitation as a technique. Proposed as a promising modulation method for a potential Far-infrared future satellite, a period of study was performed on two testbeds to improve and evolve this technique in the laboratory in order to simplify some of the technical aspects and the data analysis involved...
The development of a spectral-spatial calibration source suitable for a double Fourier modulating interferometer at infrared wavelengths, or more generally a thermal IR or spectral imager, is described. In particular a calibrator is being developed by alternating, on the emitting surface, materials of different emissivities. Its characterization and the rationale behind this choice is given, together...
