20150204655 | Optical Interferometric Apparatus for Real-Time Full-Field Thickness Inspection and Method Thereof - A device for real-time thickness inspection is provided. An optical interferometric technique is used. Measurement requirements in rapid online thickness inspection can be satisfied. An object is measured in a non-contact and non-destructive way.
