A temperature measurement system for preform fabrication by axial vapor deposition.
01 January 1984
A system has been developed for use in axial vapor deposition processes to measure the temperature profile across the growing surface of a soot preform. The system, assembled at a fraction of the cost of commercially available instrumentation, makes use of an infrared, pyrometer driven by a computer controlled stepped motor. The computer also digitizes and displays the temperature information which can be in the range of 300-1300C and acts as a controller to generate appropriate feedback signals for process control.
