Abstract
This talk reports a recent experimental study on the intensity-intensity and intensity fluctuation-fluctuation correlations of chaotic-thermal light. This study introduced a new type of detection protocol that distinguishes positive and negative intensity-fluctuations as well as the intensity and intensity-fluctuation correlation and anti-correlation from jointly measured photodetection events. Based on the observations of fluctuation-fluctuation correlation and anti-correlation of 100% contrast, a novel technology of turbulence-free imaging has been developed. This study also explored other potential applications in which the higher-order coherence is necessary to be distinguished from that of the lower-orders. In addition to its obvious importance in practical applications, this experiment brings us a new vision in understanding the physical relationships between the locally measured intensity-fluctuations and the nonlocal intensity-intensity correlation as well as the relationship between the microscopic interference and the macroscopic statistics of chaotic-thermal light.
