Image processing applied to the interactive analysis of interferometric fringes
Abstract:
A computer software system for performing interferometric fringe analysis interactively (FAI) is described. FAI is based on a general-purpose image-processing system running on a DEC PDP-11. The images contain 144 x 144 pixels with 64 gray levels. FAI permits manual definition of difficult fringe-pattern boundaries. The fringes are traced by an algorithm which makes use of the 2-D gray-level image information. The user can interactively guide the system and correct errors. The application of the system to analyzing moiré fringes defining eardrum shape is described.
