Abstract
An optical scanner employs a scanning head provided with an array of light-emitting apertures. According to one embodiment, for example, light is directed through wave-guides or optical fibers, embedded in the scanning head, to the apertures. The head is oscillated by a micro electromechanical systems (MEMS) motor. This generates a rapidly sweeping array of light spots on the scanned surface. Light is projected to a scanned surface and collected through the same apertures. In an alternate embodiment, scanning head is provided with separate optical fibers, one for each light spot. Each fiber is vibrated by a separate MEMS motor and individually oscillated in synchrony.
