Abstract:
The spectroscopic measuring instrument includes: a spectrometer to make measurement of a reflection spectrum of an object relative to a light source and output measurement information representing a result of the measurement; a shadow projector including obstacle(s) to allow light from the light source to cast shadow(s) on an object surface; an imaging device to output image information representing an image of an imaging area including the object surface; a storage interface removably connectable to a computer readable medium; and a processing device. The processing device is connected to the spectrometer, the imaging device and the storage interface, and performs a measurement process of storing the measurement information from the spectrometer and the image information from the imaging device in the computer readable medium connected to the storage interface.
