The field of matterwave interferometry, which dates back to diffraction experiments of electron beams in early days of quantum mechanics and later the separated oscillation field technique in 1950s, has become one of the most promising branches in atomic physics and quantum optics. Due to its very high potential precisions, cold atom interferometry has found fruitful applications in many fields of science and technology, especially in inertial sensor development. We briefly introduce the basic method of coherent momentum manipulation including Raman two-photon transition, Bragg diffraction and Bloch oscillation. We summarize and compare methods of large momentum transfer in atom interferometry, with a highlight on their usefulness and the latest trend of research.
