Abstract
Method and apparatus for detecting and measuring solid alien substance(s), which may adversely exist in a liquid contained in a transparent container, are provided. Light is applied to the container as it is rapidly rotated and then suddenly stopped to cause floating or suspending the solid substance(s) in the liquid. The light passed through the liquid or passed through light and also the light reflected from the solid substance(s) are separately captured and their individual intensities are measured by means of photometry. The method and apparatus may be utilized for sorting out the transparent liquid from that contaminated with solid impurity, depending upon the intensity(s) of the captured light or lights.
