Opto-electronic system for automatic track counting in plastic SSNTD

Abstract A device which consists of an optical Fourier processor, a vidicon TV camera and integrated electronics was designed. This device is efficient in track counting for SSNTD, chemically as well as electro-chemically etched. The system's optical field of view covers the complete 1×1 cm2 detector area and the count is displayed digitally. The complete processing time per detector is 1 60 s . A detailed description of the device and the counting procedure is given.
