The Zygo Laser Telemetric System is a field proven, second generation gauging system for high speed, non-contact dimension and position measurement and control. Ruggedly constructed, the system measures outside diameters, multiple dimensions or part position of either opaque or transparent objects, e.g. glass, metals, plastic or rubber, on-line and in harsh industrial environments. Many LTS's have been produced and applied. This paper reviews not only some of the interesting installations but also technical features of the Model 120 that have contributed to their success.
