PROBLEM TO BE SOLVED: To provide multi-spectral imaging device, and the like, which can illuminate, without causing unevenness in light intensity on the surface to be illuminated.;SOLUTION: This multi-spectral imaging device comprises a multi-spectral lighting system for irradiating lights of different wavelengths onto the surface of an object 4 to be illuminated, an imaging optical system 21 for imaging the light reflected from the illuminated surface and a CCD13, for analyzing the image output of this CCD13 and then measuring the color components of the illuminated surface. The multi-spectral lighting system has LEDs 23a-23h for emitting lights of mutually different wavelengths, and also has fiber unit designed as a fiber bundle 52, consisting of bundled plural fiber optics which are partitioned into incident beam bundles 51a-51h associated with each of LEDs 23a-23h on the input side; while these fiber optics are bundled integrally, in randomly mixed states on the output side that are made to be an outgoing beam bundle 53.;COPYRIGHT: (C)2008,JPO&INPIT
