Abstract: A scanning laser projector drives laser light sources with waveforms for higher efficiency. Optical light power values for pixels are mapped to amplitude/duration pairs. Laser diodes are driven with electrical currents having the amplitude for time period specified by the duration. For increasing optical light power values, amplitude values are increased, and then durations are increased.

Abstract: A scanning laser projector detects obstructions in a projector field of view using a proximity detector that detects infrared light at a photodetector. The photodetector is tested with an additional infrared light source. The additional infrared light source may also be used as proximity detector that can detect a local obstruction blocking the photodetector.

Abstract: A scanning projector includes a scanning mirror that sweep a beam in two dimensions. The beam is created by multiple laser light sources, at least two of which create light at substantially the same wavelength. A first of the two light sources is driven up to a transition point past which both of the two light sources are driven (equally or unequally).
Abstract translation: 扫描投影仪包括扫描二维扫描光束的扫描镜。 光束由多个激光光源产生，其中至少两个以基本上相同的波长产生光。 两个光源中的第一个被驱动到过渡点，两个光源都被驱动（同样或不平等）。
