REALIZATION OF GLOBAL OPTIMIZATION IN OPTICAL SYSTEM DESIGN

Variable scale method,a sort of optimal method,is used in design of optical system,meanwhile,the technique of using the ‘escape function’ for variable scale method in design is describle. It is important how to chose the values for two parameters H- and W- in the escape function,that will decide whether escape the ‘trap’ in a local minimum. A typical optical system with this technique by means of the program developed with C language was designed successfully.
