Influence the physical features of the television skanistor structures to a measurement accuracy of misalignment of the barrel pipes

Abstract

The paper considers the basic properties, mode of operation and circuitry of the television scanistor as a non-contact sensor of the measuring data in measuring devices for barrel pipe misalignment. Conditions and necessary transformations of a scanistor video signal are determined to measure the temporary location of its characteristic points that define the coordinates of light zones. Physical characteristics of scanistor operation were investigated and expressions of the error of the measured coordinate determination were achieved with their account.
