Abstract
One pixel unit including at least one light receiving element of a light receiving element array (photodiode array) and a light source have a one-to-one correspondence, and only when the light source emits light, the light beam is detected by at least one light receiving element (one pixel unit) corresponding to the light source. An illumination optical system includes a light guiding means for guiding to an inspection object by reducing an interval between optical axes of light beams emitted from a plurality of light sources in an arrangement direction of a plurality of the light sources.
