In the design of the semiconductor laser groupware,selection of lasers,design of an optical system and a laser circuit and the bonding technology are key factors.

Discussed are such a variety of topics as constant pressure mixing theory, constant area mixing theory as well as their experimental research results.

According to the matrix,it can be assured that the observation signal belongs to one of three mixtures,namely the complete mixture,over-determined mixture and under-determined mixture,and the sources can be separated from the obser.
