ABSTRACT:
Computerized electro-optical system gages two orthogonal dimensions of a moving hot bar and plots cold bar profile. Dual back-lighted electronic camera heads mounted 90.degree. apart on a scanner generate separate bar shadow pulses representing othogonal bar dimensions. Each camera source of bar pulses is processed in individual camera electronics where it is presumed the bar pulse has been corrected for optical and electronic system sources of error. If each bar pulse is not corrected, it is assumed that both a bar size pulse and bar position-in-field-of-view pulse are generated by each camera electronics and fed to a digital computer. The computer is programmed to correct for optical and electronic errors, bar temperature and composition and other errors. Two corrected bar size signals, together with a scanner position signal and a bar aim size signal, are used to plot cold bar profile deviation from aim size. CRT and printing terminals readout and printout bar profile data and interact with the computer.
