A phase shift direction of pattern light irradiated from a pattern light illuminating section is determined according to moving direction information concerning a moving direction of an inspection target object with respect to an array direction of light receiving elements and positional relation information concerning a positional relation between the light receiving elements and the pattern light illuminating section.
ILLUMINATION DEVICE FOR SPECTRAL IMAGING
An illumination system incorporating a multi-faceted mirror in operative communication with an array of discrete illumination sources. The multi-faceted mirror may accept incident light beams from discrete illumination sources located at different positions and then deliver a reflected output to a common location for direct acceptance by an optical/imaging device or by a light guide transmission device operatively connected to a downstream optical/imaging device. Individual light sources may be selected and/or combined in a defined sequence by selectively activating and deactivating such light sources electronically with no need for moving parts. By pulsing different illumination sources, the optical/imaging system may be provided with a feed of narrow-band illumination for use in imaging. Outputs from several illumination sources can also be combined if desired to produce a custom-tuned illumination spectrum for a particular application.
