Infrared single-mode fiber-optic Fourier-transform spectrometry and double Fourier interferometry
Abstract:
An infrared single-mode fiber-optic Fourier-transform spectrometer constructed for the demonstration of the technique is described, in which beam splitting and beam combining are performed with fiber-optic directional couplers and the optical path difference scan is generated by stretching fibers. Experiments done with this fiber-optic Fourier-transform spectrometer are presented. A spectral resolution of 1328 at 2.2 µm can be achieved. The experimental results show the feasibility of fiber-optic Fourier-transform spectrometry and double Fourier interferometry.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
