ABSTRACT:
An optical beam pulse generator comprises segmented reflecting means aligned to receive an input light beam. The segmented and reflecting means includes a plurality of circumferentially spaced apart mirror facets having a centrally located, vertically oriented axis of rotation and mirror facet to axis errors. The segmented reflecting means is rotated to sequentially reflect the input beam to generate a pulsed beam. A prism or similar device redirects the pulse beam back onto the reflecting means to generate a redirected pulse beam vertically displaced from the pulse beam by a distance related to the mirror facet to axis error and laterally offset from the pulse beam by a distance related to the angle between the mirror facet and the input light beam. The redirected pulsed beam is reflected from each of the mirror facets to generate a pulsed reflected output beam.
