NONDESTRUCTIVE MEASURING DEVICE FOR GREEN GROCERY

摘要

Disclosed is a nondestructive measuring device for green grocery which can prevent external light from affecting received light to thereby provide improved accuracy to the property measurements of green grocery and which can simultaneously measure beams of light at wavelengths in multiple ranges. The nondestructive measuring device (A) for green grocery includes a light-emitting section (1) for emitting light; a light-receiving section (2) for receiving diffused light; and a processing means for calculating the amount of transmitted light on the basis of the diffused light detected by the light-receiving section to compute an evaluation quantity of the green grocery from a calibration curve. The nondestructive measuring device (A) is characterized by comprising a plurality of optical sensors (61, 62) disposed on a surface of a substrate (6); a plurality of optical filters (51, 52) which are individually disposed in the vicinity of each optical sensor; a filter retainer section (5) for retaining the optical filters while individually surrounding the optical sensors; optical transmission cables (31, 32) for transmitting the diffused light detected by the light-receiving section to each optical filter; and a cable support section (4) which is connected to the filter retainer section while surrounding each end of the optical transmission cables to hold each end of the optical transmission cables.
