Abstract:
    This is a raster count device for biological group amount statistic. It includes a central control unit (11), a raster (22) and a count result output (33) which are connected with the central control unit. The raster (22) includes a correlation type light emission tube (221) and a light collection tubes group (222); the tubes of the light emission tubes group (221) and the tubes of the light collection tubes group (222) are evenly distributed around the measured biology ingress and egress path (223), and form three light correlation transducing zones which cover the ingress and egress path (223) along the X, Y, Z three directions. The central control unit (11) controls the light emission tubes group (221) and the light collection tubes (222) in sequence to conduct emission and collection. Through the ingress and egress path (223), the dimension, the moving direction and the number signals of the measured biology are modulated by the raster (22) into light emission tube and light collection tube correlation switching signals; the correlation switching signals are send into the central control unit (11) and are demodulated into the dimension, the moving direction and the number signals of the measured biology. The utility model counting device has a high checking precision, a low cost and a concealing ability.
