- Аннотация: In the present paper, we consider the issue of improving the accuracy of measurements andthe peculiar features of the measurements of the geometric parameters of objects by optoelectronicsystems, based on a television multiscan in the analogue mode in scanistor enabling. It is shownthat the convolution of the input signal of the rectangular profile of the light zone with the impulseresponse of the multiscan explains the smearing of video signal edges. The value of smearing iscompletely determined by impulse response and does not depend on the zone width. It is establishedthat signals of the action from narrow light zones are smeared out substantially relative to theirwidth, and in this case, the conventional method for determining the zone width by the videosignal derivatives stops working. A method is proposed for a full reconstruction of the rectangularprofile of a light zone (including a narrow one) in a developed noise-proof optoelectronic measuringdevice based on a multiscan with the use of spatio-structural parameters, where the width of alight zone corresponds to an extent, illumination of the zone—to brightness, and its coordinate—to centroid. It is shown that the subtraction of the dissipation of the impulse response from thevideo signal dissipation allows for accounting of the value of the video signal smearing out withhigh accuracy at the estimation of the width of a light zone, in accordance with the property of theadditive accumulation of dissipation. It is established that the use of the spatio-structural video signalmodel permits the extension of the application of multiscan-based optoelectronic devices for thehigh-accuracy control and measurement of the geometric parameters of small objects.
