Test matches may never be the same again if researchers can discover how and why cricket balls respond to different types of grass and pitch.
Across the Pennines from Old Trafford in England, a researcher from Sheffield University has developed a special-purpose high-speed stroboscopic camera to help study the way cricket balls react with the surface of a cricket pitch.
The project is supported by the pitches research group of the England and Wales Cricket Board. It is part of a larger initiative at the Sports Turf Research Institute aimed at discovering how pitch turf conditions and treatments affect playing conditions.
To achieve this, special equipment has been designed at Aberystwyth University in Wales to take samples of pitches from each of the six Test match cricket grounds in the country. Two trial areas have been set up at the institute with samples of turf taken last year from these grounds. One area is being used to determine the best soil and construction method. The other is used to compare ball performance with different grasses.
Twenty-seven trial plots of approximately 1.25 square metres, have been set up and measured for friction, hardness and wear. Cricket balls, marked for later identification, will be fired at these test areas from a bowling machine of the type used for cricket practice.
The speed, spin and angle of the ball will be recorded by two stroboscopic cameras, one for the vertical and the other for the horizontal plane, before and after it strikes the turf. Unlike earlier attempts to analyse cricket balls in flight, the images will be recorded digitally under stroboscopic light flashing on and off 350 times a second.
The cameras will be triggered by a light beam and the results stored on a hard disc. The resulting images, which can be seen on a screen, will be in the form of a "still" with a series of consecutive images of the ball passing through the field of view before and after impact. Measurements from these images taken from markings on the ball will indicate how the cricket ball reacts with different pitches. The work is not intended to lead to a standard type of pitch, but to provide a better understanding of how cricket pitches behave.
Full results of the trials are expected in three years~
