Paper Abstract

Fast-Scanning Fourier-Spectroradiometer BFS-01 was developed in Central Bureau for Unique Instrumentation of Academy of Sciences of the USSR for measuring spectral brightness of polarized electromagnetic radiation of high-temperature magnetized plasmas with high tempotal resolution in millimeter and submillimeter ranges. The instrument may be used to measure spectra from other non-stationary objects, say, for studying dynamics of transient physical and chemical processes. The spectral range of BFS-01 is from 2 to 100 cm-1 with the resolution 0.1 cm-1. The time needed to record one interferogram is 5 ms. The maximum number of interogramms (spectra) detected in one run as long as 200 ms is 20. The instrument consists of interferometer, power supply, vacuum system, radiation detector and optical commutator, which are designed as an integrated unit, and control system. The instrument and the local microprocessor controlled interfaces may be placed close to a physical facility to be studied while the personal computer may be removed to a se-parate room. The main part of the instrument is an interferometric layout (see Figure 1) in Martin-Paplette scheme allowing to detect simultaneously two interferogramms with orthogonal polarizations. The layout consists of two interferometers using one scanning device. At the input of each interferometer there are tungsten-wire grid polarizers. Beamsplitters and polarizers are also made of grids which are oriented in proper ways. Movable and immovable reflectors are dihedrons.
