Abstract

Multi-spectral images have been the basic source of information in various fields of science and technology for acquiring the multi-spectral images. After introducing a basic and simple technique of parallel Fourier spectrometry, we present the principle and experimental results of parallel techniques of ultra-fast spectral imaging. The spatially resolved interferometric data are simultaneously detected by the parallel optical systems realized by an array of small lenses. Introduced are two equivalent optical configurations realized by using a conventional Michelson interferometer and a compact interferometer incorporating wedged liquid-crystal cells. These spectral imagers have been applied to fast spectral-imaging experiments: spectral imaging of a rapidly rotating object and investigation of laser ablation of liquid. Also addressed is the coherence- based spectro-tomographic system that aims to detect the 3D spatial distribution and also the spectral distribution of scattered light in turbid media. We adopted a parallel layout of confocal optical system to exclude scattered light form the interference signals.
