Differential Digital Holography in Quality Control
This paper describes method of differential digital holography applicable in quality control for some manufacturing processes. Proposed method is able to differentiate 3D objects without production defects and similar 3D objects with production defects. Holograms of all objects are created using off-axis laboratory setup. Computer is used to compare holograms or difference holograms and determine whether the manufactured object has defect or no defect. Production defects can be in form of pattern errors or in form of surface bumps. Model of production setup for implementation in manufacturing processes is proposed.
