日本秋田新开发生产合作社开发了一种利用激光和光电二极管高精度测定积雪的新方式小型“光学式积雪仪”。把调制好的激光照射到积雪上,利用光电二极管列阵捕捉这种光的图像。通过计算,从多个
Japan’s Akita’s newly developed production cooperative has developed a new method of measuring snow with laser and photodiode high-precision small “optical snow meter.” The modulated laser light is shone on the snow, using photodiode array capture this light image. By calculating from more than one
