Optical Coherence Domain Reflectometry

Optical Coherence Domain Reflectometry (OCDR) is a technique used to measure the characteristics of optical fibers and other materials. It works by sending a beam of light into the material and analyzing the light that reflects back. By studying the time it takes for the light to return and the way it changes, engineers can create a detailed profile of the internal structure, detect flaws, or measure distances. OCDR is valuable in telecommunications, medical imaging, and materials science for assessing the integrity and quality of various materials without needing to physically alter them.
