【Abstract】 Obtaining true beautiful data from any photon correlation experiment demands on serious attention to improve the signal\|to\|noise ratio. Single\|mode optical fibers provide the ideal receiver optics for photon correlation spectroscopy measurements. The analysis shows that a single\|mode fiber can achieve a high collection efficiency and improve the signal\|to\|noise ratio effectively in photon correlation experiments. All these features are also demonstrated in experiments.更多还原
