High Efficiency Laser Modulation
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 op...

| Zusammenfassung: | 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. |
