Multiplexing decoding and coding method based on separate arrays arranged with equal interval

A multiple laser beams coding and decoding method is introduced, which is relevant to multiplexing technology in high power excimer laser systems. Based on small-angle incidence and reflection of laser beams, this method uses several separate arrays arranged with equal interval and reflecting mirrors to fulfill laser beams decoding or coding. The whole structure of the coding or decoding arrays is simple and compact, satisfying different coding/decoding width demand. The principle and characteristic of the coding/decoding method are explained by decoding of 18 laser beams with 10 ns pulse width.
