Abstract:
There is provided a wearable heads-up display (WHUD) having a laser projector to generate a display image. The display image can have a pixel having a pixel on-time. Furthermore, the laser projector can have a laser diode to emit laser light. The WHUD can also include a controller communicatively coupled to the laser diode. The controller can modulate the laser diode during the pixel on-time to be off during a laser off-time of the pixel on-time and on during a laser on-time of the pixel on-time. Moreover, the WHUD can include a holographic optical element to receive the laser light from the laser projector and redirect the laser light towards an eye of a user of the WHUD.
