Scanning laser projection display devices and methods for projecting one or more images onto a surface with a light-scanning optical fiber

A system for projecting one or more images onto a surface, the system comprising:

• a projection device comprising a light-scanning optical fiber, the projection device operable to project a sequence of light from the light-scanning fiber onto a surface according to a scan pattern;
• a laser assembly coupled with the light-scanning optical fiber and operable to generate the sequence of light;
• and
• a processor coupled with the light-scanning assembly and the laser assembly, the processor comprising a tangible medium, the tangible medium comprising instructions that when executed cause the processor to:
• generate the sequence of light in response to one or more image representations and the scan pattern comprising a varying light intensity based on a drive signal such that light intensity is varied based on both a position in the one or more image representations and a positional rate of change of the optical fiber in the scan pattern,
• articulate the optical fiber in the scan pattern based on the drive signal, in order to scan the optical fiber within a Q factor of a resonant frequency of the optical fiber such that a distal tip of the fiber has a variable velocity;
• and
• provide control signals to the laser assembly and the light-scanning assembly to increase the intensity based on the variable velocity increasing in order to project the sequence of light according to the scan pattern to form the one or more images on the surface.
