A confocal reflectance microscope system incorporates a dual-wedge laser
scanner assembly. The scanner assembly incorporates a pair of rotatably
mounted prisms, each prism having an angle selected to deviate a light
beam from a light source by a desired angle. Each prism is mounted for
rotation at a desired speed of rotation and in a desired direction to
scan the light beam over the target. An image is built up from successive
reflected signals returned from the target.
