Question 475

X is an infra-red imaging system that requires two infrared cameras on opposite sides of the ground above the field of action that are continuously recording an image. These cameras sense and measure heat from friction generated by a collision, and on occurrence of an event the infrared camera sends an image through to a computer which then turns it into negative image using a subtraction technique giving a series of black-and-white negative frames precisely localising the point of contact showing us the outcome of the recent incident. The image shows us any heat been produced in the field of action, giving us a 100% accurate conclusion on the decision. The main aim of this technology is to successfully make a decision on whether an object hit something at all. X uses technology developed in the military for tank and jet fighter tracking. The technology was adapted for television by BBG Sports. What am i talking about and what is it's significance?
