Abstract
A laser projector for projecting a 3-D image onto an object. The laser projector has an optics module, a controller module, a power module, and a timing module. The timing module coupled with the optics module measures the distance between the laser projector and the object.

A laser projection system comprising:
- a laser projection optics module having a light emitting component capable of emitting a laser beam, a focusing assembly for focusing said laser beam at some distance from said optics module, a two-axis beam steering mechanism capable of rapidly directing said laser beam over a defined surface, and a photo optic feedback component that receives said laser light reflected from said defined surface;
- a timing module coupled to said optic feedback component to determine the elapsed travel time of said laser light traveling from said light emitting component to said photo optic feedback component;
- a controller module coupled to said optics module and said timing module;
- and
- a power module coupled to said optics module, said timing module and said controller module.

A laser projector comprising:
- means for projecting a laser beam at a retro-reflective target on an object;
- means for receiving a reflected portion of said laser beam from said retro-reflective target;
- means for measuring the time of flight of said laser beam;
- means for determining the spatial position of said laser projector to said retro-reflective target using said time of flight;
- and
- means for projecting a 3-D image onto said object.

A laser projector system that projects and scans a laser beam onto a defined surface comprising:
- an optics enclosure comprising:
- a light emitting component capable of emitting a visible laser beam;
- a focusing module for focusing said laser beam at some distance from said optics enclosure;
- a two-axis beam steering component capable of rapidly directing said laser beam over the defined surface;
- and
- a photo optic feedback module that receives said laser light reflected from said defined surface;
- a controller power enclosure comprising:
- a controller module;
- and
- a power module for providing power to said controller module and said optics enclosure;
- and
- transmission means between said controller power enclosure and said optics enclosure including a timing module that converts an analog measure of the elapsed travel time of said laser beam from said light emitting component to said photoptic feedback module into a digital measure of the distance between said light emitting component and the defined surface.
