Remember the traditional tape that was stretched across the finish line of races? Since 1948, this has been replaced [READ_MORE] by photocell technology, which emits beams of light instead. As soon as the winning athlete crosses those beams, their winning time is instantly recorded. OMEGA now uses four photocells on the finish line, all integrated into one unit, allowing more body patterns to be detected. While this gives OMEGA an immediate finishing time, the official time is always taken from the photofinish camera.
