Abstract:
1. An optical testbed system for evaluating the performance of an optical component in a turbulent atmosphere, the system comprising: a computer processor with instructions for generating a time varying wavefront representing atmospheric turbulence and for inputting the time varying wavefront as a sequence of phase screens to a liquid crystal spatial light modulator; a display screen operably connected to the computer processor, wherein in operation, the display screen displays a plurality of alternative methods of generating each phase screen, the methods including a Karhunen-Loeve polynomial based method, a Zernike polynomial based method, and a frozen seeing method; and a user input device for receiving from a user and inputting to the computer processor a user-selected one of the methods, wherein the Karhunen-Loeve polynomial based method includes generating the wavefront according to: wherein for each mode i, a
