Paper Abstract

An extended method is described for continuous measurements of the size and two-dimensional (2-D) motion of single spherical particles using an image sensor. It is based on two-fold principles: the formation of a streak image of the particle from light scattered into an off-axis forward direction and the scanning detection of the streak image by a 2-D MOS imager which employs the X-Y addressing format. Unlike conventional video camera methods, all time-resolved information of the particle size and motion can be determined by evaluating the intensity distribution of one frame image with an attainable time resolution of 63.5 μs.
