在苹果中安家的蛀虫将遇到劲敌。物理学家已研制出一种基于分光技术的水果鉴定仪器,例如,它能找出具有蛀洞的苹果,把低质量的水果从大批水果中挑选出来。 把一个很短的激光脉冲射入一只苹果,根据光束的瞬时畸变和衰减,研究人员可获得关于果浆的吸收和散射特性的信息。这种时间分辨反射分光技术是一种无损技术,而且几乎不受苹果皮中的变量的影响。吸 Assholes in the apples will encounter rivalries. Physicists have developed a fruit-identification instrument based on spectroscopic techniques, for example, it can find apples with wormholes and pick low-quality fruits from a large number of fruits. By injecting a short laser pulse into an apple, researchers can obtain information about the absorption and scattering properties of the pulp, based on the instantaneous distortion and attenuation of the beam. This time-resolved reflectance spectroscopy technique is a non-destructive technique that is virtually unaffected by the variables in the apple peel. Suck
