Abstract
An inexpensive remote-controllable laser projection apparatus projects a laser light onto a target object that is located at a prescribed distance from the laser projection apparatus. The laser projection apparatus includes a main body and a remotely controllable reflection target. The main body includes a projection means for projecting the laser light, a reflected light detection means for detecting the reflected light of the projected laser light, a controller, which is connected to the projection means and the reflected light detection means, for controlling the projection of the laser light in multiple operation modes. The reflection target is placed at a position that is separated from the main body, on which prescribed reflection patterns for reflecting the projected laser light are formed. The controller detects, via the reflected light detection means, the patterns of the reflected light which are generated by the reflection patterns formed on the reflection target, and the controller identifies and selects the operation mode based on the detected patterns of the reflected light.
