Abstract
A scanning laser projection system includes a virtual protective housing circuit to automatically reduce power levels of visible laser light pulses when necessary to render the laser projection system eye-safe. IR laser light pulses are scanned out in front of visible laser light pulses in a field of view, and emitted power of visible laser light pulses is modulated based on attributes of reflections of the IR laser light pulses.
