Interferometry and Coherence

This lecture covers the principles of coherence and interferometry, focusing on statistical optics, theory of optical coherence, and interferometer types. It delves into the concepts of stationarity, ergodicity, autocorrelation functions, and complex degree of coherence. The lecture also explores applications in surface testing, Newton fringes, and multiple beam interference. The discussion extends to optical coherence tomography, Fourier domain OCT, and time domain interferometry, with a glimpse into astronomical interferometry and LIGO's gravitational wave detection.
