EvolutionCharacteristics of the Kurtosis Parameter on a Distorted Cat's Eye Effe

Based on the definition of second order moment, fourth order moment and the approximate three-dimensional analytical formula for oblique laser beam passing through a cat's eye optical lens with centre shelter, the analytical expression of kurtosis parameter of the cat's eye effect reflected light under far field condition has been deduced. Evolution characteristics of kurtosis parameter affected by the incident angle, back backhaul transmission distance, local shift and centre shelter ra
