Paper Abstract

Interferograms in the form of fringe patterns can be produced in two-beam interferometers, holographic or speckle interferometers, in setups realizing moire techniques or in deflectometers. Optical metrology based on the principle of interference can be applied as a testing tool in biomedical research. By analyzing of the fringe pattern images, information about the shape or mechanical behavior of the object under study can be retrieved. Here, some of the techniques for creating fringe pattern images were presented along with methods of analysis. Intensity based analysis as well as methods of phase measurements, are mentioned. Applications of inteferometric methods, especially in the field of experimental orthopedics, endoscopy and ophthalmology are pointed out.
