Abstract:
Laser safety systems, devices, and methods for use in laser projectors are described. A laser projector includes any number of laser diodes that each emit laser light, a laser diode power source, a current sensor to detect a magnitude of the electric current output by the power source, a photodetector to detect a power/intensity of the laser light, a beam splitter to direct a first portion of the light towards the photodetector and a second portion of the light towards an output on the projector, and first and second laser safety circuits responsive to signals from the photodetector and the current sensor, respectively. The laser safety circuits selectively electrically couples/uncouples the laser diodes from the power source depending on signals from the photodetector and/or the current sensor. Particular applications of the laser safety systems, devices, and methods in a wearable heads-up display are described.

Claim (Index 6):
The method of  claim 1  wherein the second laser safety circuit includes a second latch that is communicatively coupled to the current sensor and to the second switch, a state of the second latch responsive to the signal from the current sensor and the second switch responsive to the state of the second latch, and further comprising:\n in response to the signal from the current sensor indicating that the electric current output by the power source exceeds the second threshold, changing, by the second latch, the state of the second latch from a first state to a second state; and \n wherein interrupting, by the second switch, a supply of power to the at least one laser diode from the power source includes interrupting, by the second switch, a supply of power to the at least one laser diode from the power source in response to the state of the second latch changing from the first state to the second state.
