An attempt has been made to employ a linear photo-diode array (so-called an image sensor) , such as the one used as the image pick up element in picture analysis or facsimile telegraphy, for simultaneous determination of the diameter and velocity of moving solid particles. An optical microscope was used in this study. Transparent glass spheres having 120〜310 micron diameter were placed in rows on the movable stage of the microscope, which was moved at a constants speed. The images of moving glass spheres were detected with an image sensor attached on the top of microscope. After A-D conversion of the output signals of the sensor, they were fed into a miniature computer, where each particle diameter and velocity were calculated. The results showed the possibility of making general use of image sensors for accurate measurements of the size and velocity of solid particles in motion.
