摘要

A total of 100 beams emitted from 100 stripes, with an 80-mu m aperture spaced on 100-mu m centers, of a 1-cm linear diode array were collimated by a multiprism array consisting of 15 800-mu m-wide prismlets. The spatial intensity distributions of each eight-beam unit were rotated 90 degrees through three total reflections in a prismlet. The array of prismlets transforms a long dotted line (a long line array of emitters) to a series of short dotted hues arranged in parallel. Collimated beams were focused to a spot of similar to 500 mu m (FWHM). (C) 1997 Optical Society of America.
