DETERMINATION OF THE WORKING AREA FOR THE CORNER-CUBE MIRROR SYSTEM WITH VARIABLE-ANGLE OF INCIDENT BEAM FOR INTERFEROMETRIC APPLICATIONS

A configuration of three-mirror retroreflecting system used for changi ng the optical path in the interferometric system is discussed. The pr opagation of the incident beam after successive reflection is analysed . The influence of the position and inclination of the entering beam o n the real working area on each of the three mirrors of the system is taken into account The collision of the beam with minor edges is avoid ed. The analytical solution of the problem together with rotation kine matics of the retroreflector system is presented.
