ABSTRACT:
An apparatus is disclosed for chopping a beam of radiant energy into three or more pulse trains propagating in different directions. The apparatus includes a disc rotating in a plane normal to the incident beam, having a circular pattern of reflective and transmissive portions. The reflective portions include first and second sets of surfaces inclined respectively at first and second oblique angles to the plane of the disc, for reflecting energy in first and second directions.
