Based on optical Fourier transform, the online measurement of the sizes of standard wire sieves is described. Compared with other traditional methods, this system has more advantages, such as operating efficiently and precisely on line and in real time. The measuring system, composed of a laser, an optical Fourier transform system, a CCD camera, an image acquisition system, and a personal computer, can offer averaged sizes and percentage of apertures exceeding the specified size of standard wire sieves in two-dimensional directions. The experimental results are also presented.
