A semiconductor laser is fired at a rotating polygon mirror and scans through the measurement range. Measured values are calculated by measuring how long the laser is obstructed by the target
light is emitted as a uniform collimated beam. The CMOS sensor accurately detects the position of the edge between light and dark edges of the received light and determines the measured values
