Laser projection system has security mechanisms
2012
A laser projection system, comprising: a laser light source emitting a laser light; and a human body detecting module for detecting a reflected light of the laser light is projected to an object. The human body detection module according to a complex relationship between the reflectance of the reflected light to determine whether the object is a human. If so, the human body detection module to control the laser source output intensity of a laser-cut.
