    • PROBLEM TO BE SOLVED: To provide a method for detecting a foreign substance such as a parasite and others, especially a method for detecting the parasite in such a state that it is parasitic on meat.
      SOLUTION: The method for detecting the foreign substance is characterized in that the foreign substance such as the parasite and others is irradiated with a visible light, and an excited fluorescence is detected. The method is suitable for detecting the parasite in such the state that it is parasitic on the meat. The method for detecting the parasite is characterized in that the fluorescence emitted from the parasite is detected selectively by using a filter which does not transmit any exciting light but transmits the fluorescence emitted from the parasite. The method for detecting the parasite is composed of: a light source for irradiating an object to be tested with the visible light having a specific wavelength; the filter for absorbing exciting light reflected irregularly; a camera for photographing the fluorescence from the parasite; an image processing apparatus; and a monitor.

    • 要解决的问题:提供一种检测诸如寄生虫等的异物的方法,特别是一种在寄生在肉上的状态下检测寄生虫的方法。 解决方案:用于检测异物的方法的特征在于用可见光照射诸如寄生虫等的异物,并且检测到激发的荧光。 该方法适用于在寄生在肉上的状态下检测寄生虫。 用于检测寄生虫的方法的特征在于,通过使用不透射任何激发光但透射从寄生虫发出的荧光的滤光器来选择性地检测从寄生物发出的荧光。 用于检测寄生虫的方法包括:用具有特定波长的可见光照射待测物体的光源; 用于吸收不规则反射的激发光的滤光片; 用于拍摄来自寄生虫的荧光的照相机; 图像处理装置; 和监视器。 版权所有(C)2008,JPO&INPIT
