Integrated microspectrometers implemented in silicon photonic chips have gathered a great interest for diverse applications such as biological analysis, environmental monitoring, and remote sensing. These often demand high spectral resolution, broad operational bandwidth, large optical throughput. Spatial heterodyne Fourier-transform (SHFT) spectrometers been proposed to overcome the limited th...

SCISAT-1, also known as the Atmospheric Chemistry Experiment, is a satellite mission for remote sensing of the Earth's atmosphere, launched on 12 August 2003. The primary instrument on the satellite is a 0.02 cm(-1) resolution Fourier-transform spectrometer operating in the mid-IR (750-4400 cm(-1)). We describe the approach developed for the retrieval of atmospheric temperature and pressure fro...

The Cupric oxide (CuO) nanostructures and Fe doped CuO nanomaterials are synthesized by microwave irradiation method. effect of doping on the crystal structure, band gap optical properties samples were characterized using x-ray diffraction, ultraviolet-visible spectrometer, photoluminescence spectrometer Fourier transform infrared spectrometer. X-ray diffraction study confirms size particle in ...

The high resolution and low measurement uncertainty goals for next generation atmospheric sounders will require FTSbased spectrometers which exhibit improved velocity stability and disturbance rejection over previous systems. This paper documents the characterization of and improvements made to existing SDL FTS systems as part of an internal study to meet the demands of future missions. Improve...

Complex domain calibration is an efficient method to correct the amplitude and phase of a spectrum obtained from a Fourier transform spectrometer. This method is, however, not directly applicable in the occurrence of a zero path difference (ZPD) shift between a scene interferogram and calibration blackbody interferograms. This situation is likely to happen for a system with thermal instabilitie...
