ABSTRACT:
A method for computerized control of vapor deposition processes, including chemical vapor deposition and electron beam physical vapor deposition processes, uses optical imaging sensors and/or laser interferometers or infrared ellipsometers focused on the substrate being coated or on a nearby test blank to provide information which is computer analyzed to yield optimum control points for the coating process. A method is also disclosed for shaping or contouring one or more surfaces of an object(s) using the techniques disclosed here.
