1. Hawk-Eye


Hawk eye, technology by which ball is traced

    The system (Owned by Sony) is originally developed in the United Kingdom and widely used in sports as it accurate within 3.6 mm. It is used in many sports to track the ball and display a profile of its most likely path as a moving image. It works via many cameras (Usually six or more, positioned on the roof of the stadium) to track the ball from various angles.


2. Radar Gun or Speed Gun

    Have ever wonder How the Speed of the ball is measured? The concept is quite similar to measuring the speed of vehicles. The system consists of two elements, Reciever and Transmitter. With the transmitter Radio wave is transmitted and is reflected by the ball which is received by the receiver. The system calculates the difference based on the principle of Doppler shift and gives the speed of the ball.
