AUTOGIDING OPTICAL-MECHANICAL SYSTEM OF FIBER-OPTIC SPECTROGRAPH WITH COUNTER LIGHTING OF OPTICAL FIBER

摘要

FIELD: physics.;SUBSTANCE: autoguiding optical-mechanical system with counter lighting of optical fiber has optical fibre, which connects an input system and the optical system of a spectrograph and a detector of shifting the image of the star center from the input end of the optical fibre. Herewith the optical fiber input is glued in the center of one of the faces of the optical prism. And in front of the optical prism there are two compensating optical elements in the beam course, made in the form of plane-parallel plates, each of which has the ability to rotate about its axis. The axes of the optical elements are located in orthogonal planes, and their drives are made in the form of electric motors controlled by a personal computer through a special algorithm.;EFFECT: simplification of design and manufacturing technology of the autoguiding optical-mechanical system of the optical spectrograph based on counter lighting of the optical fiber.;1 dwg
