Researchers at Louisiana State University (LSU) are taking advantage of the quantum properties of light to design the world’s most sensitive optical interferometer. Optical interferometers are used in a vast range of applications, including metrology, surface profiling, microfluidics, mechanical stress/strain measurement and velocimetry. These instruments operate by combining two or more light sources (typically laser light) so that interference fringe patterns are produced. Information derived from such fringe measurements is used to determine precise wavelength and to measure...Read full article

    mach-zehnder interferometer
    A Mach-Zehnder interferometer is an optical device used to measure the phase difference between two collimated beams of light. It is named after the physicists Ludwig Mach and Ludwig Zehnder, who independently proposed the design in the early 20th century. The Mach-Zehnder interferometer consists of a beamsplitter, two mirrors, and two beam combiners. Here is a basic description of its components and operation: Beamsplitter: The incoming light beam is split into two beams by a...
    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
