Abstract
Briefly, in accordance with one or more embodiments, a scanned beam projector comprises a laser diode to emit a beam, a scanning engine to scan the beam on a surface to project an image comprising virtual pixels on the surface, a digital-to-analog converter (DAC) coupled to the laser diode to cause the laser diode to emit the beam in response to a digital video signal provided to the DAC, and a pulsed pixel controller to provide the digital video signal to the DAC, the pulsed pixel controller to align the digital video signal provided to the DAC with the virtual pixels of the image, and to select an optimal waveform to be generated by the laser diode for each virtual pixel.
