英文摘要 | In order to characterize optical turbulence, we have developed a single star SCIDAR (SSS) for measurement of the distribution of C (n) (2) with height. The SSS consists of a 40 cm telescope and a CCD camera for fast sampling of stellar scintillation pattern. Spatiotemporal auto and cross-correlation functions of the single star images are computed, providing vertical profiles of optical turbulence intensity C (n) (2) (h) and wind speed V(h). Using this new SSS experiment, profiles of turbulence can be obtained from the ground to the top of atmosphere, allowing the determination of seeing, isoplanatic angle and coherence time. Detailed characteristics of atmospheric optical turbulence are important for active and passive imaging, astronomical site testing, adaptive optics, laser communications, target tracking and designation, and laser beam control. We plan to improve the robotization of the SSS to be able to use it routinely even under harsh weather and altitude conditions that we expect to encounter on the high Tibetan plateau or at Dome A in Antarctica. SSS will also be applied for the site testing campaign of the future Chinese extremely large telescope. |
