What Does HBT Stand For?
HBT stands for Hanbury Brown Twiss Interferometry
HBT, or Hanbury Brown Twiss Interferometry, is a technique used in quantum optics and astrophysics to measure the second-order correlation functions of light. Developed by physicists Robert Hanbury Brown and Richard Twiss in the 1950s, this method allows for the analysis of the statistical properties of photon emissions from sources. It is particularly notable for its application in determining the brightness and size of astronomical objects, as well as in advancing the understanding of quantum phenomena. HBT interferometry plays a crucial role in various fields, including imaging, sensor technology, and quantum information science.
