住友金属矿山公司开发出用激光挑选含糖苹果或洋梨的系统。将激光通到果实内部，测定蜜成分引起的吸收，用以判别蜜的有无。用一台传感器便能测定甜瓜、桃、苹果、洋梨、西瓜的糖度。如果对测定数据的分析方法加以改进，还能检测内部的疾病和生理障害等。标准的测定速度为２个? Sumitomo Metal Mining has developed a system that uses lasers to pick up sugary apples or pear. Pass the laser to the inside of the fruit and measure the absorption caused by the honey component to determine the presence or absence of honey. With a sensor can be measured melon, peach, apple, pear, watermelon brix. If the measurement data analysis methods to be improved, but also detect internal diseases and physical disorders.
