<p><P>PROBLEM TO BE SOLVED: To provide a small-sized and inexpensive agricultural product internal quality measuring device for outdoor use which can accurately measure the internal quality of an agricultural product. <P>SOLUTION: This device includes: an inner shielding wall 11 and an outer shielding wall 12 which are cylindrical and projected from one surface of a body 10; a photodetection part 2 for detecting intensity of light entering from a tip opening of the inner shielding wall, and outputting a light intensity signal of a value corresponding to the intensity; and a single wavelength light emission part arranged on an arrangement surface between the inner shielding wall and the outer shielding wall, for emitting a plurality of lights having each mutually different peak wavelength. In the device, each single wavelength light emission part is switched successively and lit, and the internal quality of an agricultural product is calculated based on relative intensity of each light passing through the agricultural product from each single wavelength light emission part, and detected by the photodetection part, and an auxiliary light emission part 4 for emitting light having a wavelength different from the wavelength of the light emitted from each single wavelength light emission part is further provided, to thereby light the auxiliary light emission part simultaneously with each single wavelength light emission part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
