Abstract

PURPOSE:To obtain reflection quantity from the time of the integrated outputs of reflection light and perform measurement of high accuracy at high speed in inspecting the maturity, etc. of fruits by radiating green light and red light to the surface skin of the fruits and discriminating the hue of the surface skin from the ratio of the reflected light of both rays.
