Optical metrology based on the principle of interference can be applied as a testing tool in biomedical research. Interferograms in form of fringe patterns can be produced in two-beams interferometers, holographic or speckle interferometers, in setups realizing moire techniques or in deflectometers. 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. Possible applications of interferometric methods, especially in the field of experimental orthopedics, endoscopy and ophthalmology will be pointed out.
