Abstract
Systems and methods are provided for controlling and/or modifying operation of a red, green, blue (RGB) laser assembly for creating images in mixed-reality environments. Initially, the lasers in the RGB laser assembly operate in a low power or non-emitting state. Then, the lasers emit laser light to illuminate a pixel or a group of pixels. This illumination occurs for a period of time spanning less than 15 nanoseconds. By causing the lasers to emit laser light only during this short period of time, the resulting laser light is structured with a reduced spatial coherence level. Once the time period elapses, then the lasers again return to the non-emitting state. This process repeats for each pixel such that the lasers generate pulsed emissions. By operating the lasers with a reduced spatial coherence, undesired visual artifacts can be reduced or eliminated within the target display area.
