  • Laser projector and method of detecting scanning angle range of laser beam thereof
    Patent number: 8905553
    Abstract: A method of detecting a scanning angle range of a laser beam of a laser projector is provided. First, a photo sensor is disposed between first and second positions on a projection mirror. Then, a laser beam emitted from the laser projector scans back and forth between the first and second positions, so that the photo sensor receives the laser beam sequentially at first and second scanning time points to generate first and second sensing signals, respectively. If an actual time interval between the first and second sensing signals conforms to an expected time interval, an actual scanning angle range of the laser beam is determined as normal. If the actual time interval does not conform to the expected time interval, the actual scanning angle range of the laser beam is determined as abnormal and the laser projector stops emitting the laser beam. A laser projector is also provided.
