Abstract

In order to help shot athletes improve their score quickly,a new shot motion parameter measuring system was designed. The system consists of a set of laser parallel light curtain based on Fresnel lens and photodiode array, using field-programmable gate array (FPGA) for processing signals. The method can measure the shot angle and velocity conveniently and display the measurement results on the liquid crystal display(LCD) monitor intuitively. The results show that the system design is novel, structure-simple and low-cost,which can be used by athletes for daily training and has wide application prospects.
