Abstract
Out of focus images recorded separately by two CCD cameras viewing the same object field are processed to measure simultaneously the size, 3-D position, and velocity of particles. The sign ambiguity of defocusing is removed by introducing a shift on the axial location of one camera with respect to the other and by using the ratio of the Fourier transforms of two defocused images. Particle sizing procedure includes mainly a calibration of the point spread function (PSF) of the optoelectronic setup for different amounts of defocusing and the measurement of both the contrast and the width at the intensity mid-point of defocused images.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
