Abstract
There is described an optical system for sensing the surface of an object. The system comprises: a light source for emitting at least one light beam centered on the optical axis of the system; a light reflector for reflecting the at least one incident light beam to generate at least two hollow conical light beams centered on the optical axis and having different opening angles, the at least two reflected hollow conical light beams for illuminating the surface; and an image capture device for imaging the illuminated surface.
