摘要

The device has an optical transmitter and receiver with a rotating deflector with mirrors and a window (2) in a housing (1). The window is formed as a spherical section (18) whose mid-point is the intersection of the rotation axis (10) and the optical axis of incident and outgoing light beams (5,16). The transmission mirror (11) and the perpendicular reception mirror (12) are arranged at an angle of 45 degrees to the axis of rotation (10).
