Abstract
The article discusses the construction of hyperspectral systems based on the Fabry-Perot interferometer using a black-and-white matrix sensor that registers image signals during scanning of a given spectral range. Image generation methods based on preliminary scanning of a given range of the spectrum, storing the resulting images and subtracting these images from the images obtained during the current scan are described. The gain is estimated, which consists in expanding the range of spectral scanning in single-mode mode. The scanning parameters for several variants of the compensation process using different interference orders are considered in detail, and the results of their computer simulation are discussed, as well as recommendations for their application. The article discusses in detail the parameters of scanning the spectral range. The corresponding formulas, tables, and illustrations are provided, showing the sequence of image acquisition to compensate for additional modes that appear during the scanning process.
