The Development of a Laser-Operated Scanning Rod Gauge
Unsatisfactory tests on a rod gauge using bar radiation led to the adoption of a scanning gauge using back illumination. The chosen design employs a helium-neon laser and a multi-face mirror rotated by a synchronous motor driven by a crystal-controlled oscillator. Digital counting techniques are emp...
