<p>The system involves placing a plurality of small-sized modules (3) under the ice layer (1) that forms the rink. Each module is provided with at least one illumination lamp and a detector for activating said lamp during the passage of the puck (2), which in turn is provided with the corresponding emitter in such a way that as said puck (2) travels on the ice rink (1), it excites the corresponding modules (3') along its trajectory and generates therewith a luminous 'line' (4) enabling easy identification of the trajectory of the puck (2), the length of said line additionally providing information on the speed of said puck (2).</p> |
