Interferometers as a research area encompass the theoretical, experimental, and technological study of instruments that exploit interference of coherent waves—primarily optical, but also matter, microwave, and gravitational waves—to achieve high-precision measurement and sensing. This field investigates configuration design (e.g., Michelson, Mach–Zehnder, Fabry–Pérot), coherence and stability requirements, noise sources and mitigation, signal extraction techniques, and quantum-limited measurement strategies. Research spans applications in metrology, gravitational-wave detection, inertial sensing, spectroscopy, and fundamental tests of quantum mechanics, often integrating advanced lasers, optical cavities, photonic integration, and quantum optics (squeezed states, entanglement) to enhance sensitivity and resolution.
What's on and in a star? What happens in an active galactic nucleus? Answering those questions is the goal of a proposed giant interferometer on the moon. It's called the Artemis-enabled Stellar Imager (AeSI) and would deploy ...
