Abstract
Computerized electro-optical system gages dimension of a moving hot bar. Back-lighted electronic camera head generates high-speed bar shadow pulses which represent the bar dimensions. Bar pulses are processed by way of camera electronics and a digital computer. CRT and printing terminals, interacting with the computer, indicate and/or record a recalibration mask table and a cold-size bar diameter measurement. Camera head electronics includes camera AGC, a digital type one-axis bidirectional linear sweep, bar pulse edge-detection with an autocorrelator to remove noise and enhance the bar pulse, and a digital accumulator of digital bar size signals. The digital computer assimilates bar size along with bar temperature, aim size, and other data signals. The computer is programmed to: (a) compensate bar size signals for bar temperature; (b) calibrate the gage off-line and automatically recalibrate the gage on-line to correct for drift and slope errors; and (c) communicate with the CRT and printing terminals and an exterior control system.
