ABSTRACT:
A laser beam projection apparatus is capable of supplying laser beams finely converged on an object at all times irrespective of a distance to the object. The laser beam projection apparatus has a laser beam generator, including a focus adjusting device, for supplying laser beams periodically swept within one plane and, at the same time, converged at a controllable distance, a light receiving element for receiving reflected laser beams from a predetermined object and generating an output signal, a distance calculating unit for calculating a distance to the object on the basis of the output signal and a controller for operating the focus adjusting device so that the swept laser beams are converged in a position corresponding to the calculated distance. The controller can change a sweep speed of the laser beam in accordance with a change in the calculated distance. The controller cna change a sweep speed of the laser beam in accordance with a change in the calculated distance.
