FIELD: engineering of devices for changing direction of a light beam in optical and mechanical routes of laser systems. ^ SUBSTANCE: device for scanning by a light beam contains two transparent plates positioned in the body and connected along perimeter by resilient-elastic element with creation of a hollow, filled with optically transparent substance. One plate is held in a frame with spherical side surface positioned in body hollow, mounted with possible inclination and equipped with angular movement mechanisms. Spherical frame of moveable plate is made with a circular fillet, and in the body on sides of plates two pairs of diametrically oppositely positioned posts are provided with ends, bent towards the fillet of spherical frame, and bent ends of two adjacent posts are mounted with possible movement along aforementioned posts. Angular movement mechanisms are positioned between circular fillet of spherical frame of mobile plate and moving ends of two adjacent posts, and resilient elements are installed between immoveable ends of posts and circular fillet of spherical frame. Body hollow is made with conical section for interaction with spherical surface of frame of mobile plate. ^ EFFECT: increased precision of deviation of light beam when it is used for scanning of a space. ^ 3 cl, 3 dwg |
