New applications of Fourier spectrometers

This paper discusses the main stages of the development of Fourier spectrom etry. Certain technical characteristics of the Fourier spectrometers develo ped at GOI are presented. The main types of attachments used for Fourier sp ectrometers are given: microscopes. diffuse-reflection attachments. multipa ss gas cells. frustrated-total-internal-reflection attachments. multiple-fr ustrated-total-internal-reflection attachments, and photoacoustic cells. Th e possibilities of using multiarea detectors in both dynamic and static Fou rier spectrometers are indicated. Methods are proposed for using, Fourier s pectrometers with multiarea detectors as the coding element and as the wave front sensor in video spectrometers. (C) 2001 The Optical Society of Americ a.
