Real world close loop optical design system which include the software design program and the hardware optical bench with stock lens set as well as image procesor with image testing equipment. The datum of optical lens distance are input to the program by digit meter which connected to the lens holder in the bench. The datum of the index of refraction and the lens curvature of stock lenses are stored in the lens library subroutine with code number in order easily to key in. According to the optical design program, servomotors drive the lens holders to suitable positions. The result of update optical system are checked by the resolving power projector to project test pattern through optical system to screen to be inspected and processed by TV camera and image process system. The value of the square wave transfer functions are calculated and feed back to the optical design program to suggest the direction for the next turn of optimization.
