Abstract
A combined semiconductor laser and photodetector with a photodetector arranged to directly monitor light reflected off an object surface from the semiconductor laser. A photodetector is mounted in the same plane as the surface of the semiconductor laser which emits light. This plane is substantially perpendicular to the central axis of the cone of light emitted from the semiconductor laser. The photodetector and the semiconductor laser are both mounted within a single housing.
