Claim:
1. A method for projecting a composite image to a target area, comprising: scanning an optical fiber assembly in a scan pattern so as to provide illumination to the target area, the optical fiber assembly comprising a plurality of optical fibers optically coupled to an optical system to focus light from the optical fiber assembly and produce a plurality of focal planes located at different distances with respect to an optical axis in the optical system; modulating the intensity of the provided light based on an image to create variation in light intensity across the target area; and projecting, based at least in part on the illumination provided to the target area, a composite image based on the image onto the target area, the composite image having a depth of field spanning over a distance between the plurality of focal planes.
