Abstract

A detection system for detecting the position of an object on a movable memb er and particularly for detecting the position of a ball in a moving roulette wheel (1, 4) comprises a light source (13, 14, 15) to e mit visible light which is modulated. A sensor (16) is p rovided to receive reflections by the ball and the moving roulette wheel (1, 4) of s aid emitted modulated light. The reflections are analyse d by appropriate means to determine the position of the member (4) and the locati on of the object in relation thereto. The light source ( 13, 14, 15) may transmit white light and the sensor (16) detect specific similarly m odulated wavelengths, which are predetermined dependent on the relative chrominance of the numbers ring and the pockets ring (6) of the wheel (1, 4), and the object. Alternatively, the light source (13, 14, 15) may transmit light of specific wavelengths which are predetermi ned dependent on the relative chrominance of the numbers ring and the pockets ring (6) of the wheel (1, 4), and the ball, and the sen sor (16) may detect similarly modulated wavelengths over the broadband visible light range.
