Abstract:

Subject of study. Methods for designing unified optical schemes of acousto-optical imaging spectrometers for various purposes. Aim of study. Creation of a unified optical scheme that works with both single and double acousto-optical monochromators without declining image quality. Method. The presented method for designing optical schemes of acousto-optical imaging spectrometers consists of two stages: the formation special multiconfiguration and optimization parameters in the computer-aided design of optical schemes for calculating the optical scheme and subsequent spatial-spectral calibration of the finished acousto-optical imaging spectrometer. Main results. A small-sized reconfigurable imaging spectrometer in the visible range of spectrum with an acousto-optical monochromator in parallel beams of aperture rays is presented. A feature of this device is a unified optical scheme that can work with both a single and a double acousto-optical monochromator. The stages of designing the acousto-optical imaging spectrometer are described, and the features of calculating the unified optical scheme are indicated. The analysis of the calculated unified optical scheme is carried out. The image quality of the optical scheme is estimated for two configurations. The configurations of the unified optical scheme with double and single monochromatization are compared. It is shown that the single acousto-optical monochromator can operate in an enlarged angular field of view with a preliminary specialized spatial-spectral calibration. The features of these configurations of the acousto-optical imaging spectrometer and the possibility of their application in the implementation of spectral instruments for solving various applied problems are presented. Practical significance. The results of the work can be used in the design of unified optical schemes suitable for use with both single and double acousto-optic monochromators without declining image quality.
