用激光判断鱼的新鲜度汪期达日本长崎水产公司，最近开发出一种利用激光测定鱼眼反射光变化来测定鱼新鲜度的新技术。实验中发现，刚死的鱼眼反射光量最多、周波数最高。随着时间的延长，鱼眼反射的光量逐渐减少，周波数慢慢下降。该研究成果为广大消费者提供了方便。用激... Using laser to determine the freshness of the fish Wang Dagang Nagasaki Aquaculture Co., Ltd. of Japan recently developed a new technique for determining the freshness of fish by measuring the change in fish-eye reflections with a laser. The experiment found that just died fisheye reflected light the most, the highest number of cycles. As time goes on, the amount of light reflected by the fisheye gradually decreases and the number of cycles slowly decreases. The research results provide convenience for consumers. With shock ...
