ABSTRACT:
An adaptive imaging telescope having a linear sensor for detecting a received optical image. The system includes a choice of two electro-optic phase shifters positioned substantially at the aperture of the telescope responsive to the received optical image. The linear sensor may consist either of a pinhole detector, a transform circuit such as of the Fourier type, or a video camera with computation circuits. This system also includes circuits responsive to outputs from the linear sensor feeding the phase shifter in closed-loop arrangement.
