摘要:
A turbulence-free CCD camera system with nonclassical imaging resolution, for applications in long-distance imaging, such as satellite and aircraft-to-ground based distant imaging, utilizing an intensity-fluctuation correlation measurement of thermal light. The proposed camera system has the following advantages over classic imaging technology: (1) it is turbulence-free; (2) its spatial resolution is mainly determined by the angular diameter of the light source. For example, using sun as the light source, this camera may achieve a spatial resolution of 200 micrometer for any object on Earth. 200-micrometer resolution is insignificant for short distance imaging, however, taking a picture of a target at 10-kilometer, a classic camera must have a lens of 90-meter diameter in order to achieve 200-micrometer resolution. Unlike a classic camera, the proposed turbulence-free CCD camera system has adequate spatial resolution zoom a long distance and still distinguish the objects within a small area, even with a small lens.
