Abstract

A method for obtaining 3-D images by illuminating an object with frequency tunable laser light and recording information interferometrically is discussed. The instrumentation requirements include a telecentric imaging system and a tunable laser source capable of serially illuminating the object with multiple laser frequencies. Complex-valued image plane data is recorded interferometrically and processed using Fourier transform algorithms, and 3-D images obtained from a variety of objects are presented. These results demonstrate the wide range of measurement applications that can be addressed with this method. © 2000 Society of Photo-Optical Instrumentation Engineers.
