Computerized electro-optical system gages two orthogonal dimensions of a moving hot bar at various peripheral positions. Dual back-light electronic camera heads mounted 90 DEG apart on a scanner generate high-speed bar shadow pulses which represent the bar dimensions. Bar pulses are processed by way of individual camera electronics and a digital computer. CRT and printing terminals, interacting with the computer, indicate and/or record each cold-size bar diameter measurement, a plot of bar profile deviation from aim gage overlaid on full- and half-commercial tolerance references with a data header, and a gaging system histogram. |
