FIELD: instruments, in particular, multiple-channel classification systems. SUBSTANCE: device has N calculation channels each of which is designed as serial circuit of current pulse generator and commutator. Outputs of each calculation channel are connected to corresponding indicator which is designed as line of optoelectronic pairs, which illumination units have additional optical output. Lines are located in radial direction at equal angular distance on surface of flat, circle-shaped screen which is made from sheet material which scatters light by diffusion. opposite side of screen is connected to optical unit which has at least one generator of light beam and units which change its diameter. Outputs of generators of current pulses are connected to corresponding inputs of N-channel counter which output is connected to units, which change diameter of light beam, through serial circuit of divider and final-control mechanism. Divider can change level of divisor; optical axis of generator of light beam is perpendicular to screen surface an d runs through its center. EFFECT: simplified detection of characteristics of classification of objects. 3 cl, 3 dwg |
