Abstract
A laser diode ( ) emits laser light which is collimated into parallel rays with a collimating lens ( ). The collimated beams travel about 5 to 50 cm before being reflected back to an adjustable mirror ( ), to a fixed mirror ( ), and then on to a photoreceiver ( ). The adjustable mirror ( ) is pivoted by turning an adjusting screw ( ). The adjustable mirror ( ) has a toothed cam ( ) on its backside that mate with the threads of the adjusting screw ( ). When the adjusting screw ( ) is turned, it forces the cam to move with it, thus changing the angle of the adjustable mirror ( ). A ball lens ( ) focuses the reflected light onto the photoreceiver ( ). The photoreceiver ( ) and laser diode ( ) are synchronized so that the receiver ( ) can only receive light during appropriate windows of time corresponding to when the laser light was emitted. The photoreceiver ( ) has the ability to tell when it is and when it is not receiving laser light and has the ability to initiate action based upon that information.
