MEASUREMENT OF PARTICLE SIZES |
摘要 |
The size of particles moving in a confined path is measured by moving the particles through an interference pattern of fringes produced by a pair of coherent light beams. The periodic fluctations in the light intensity as the particles move across the fringes are recorded on a fixed photodetector and the particle size is derived from a measurement of the magnitude of the fluctuations.
