Fabry-Perot Standard: Principles and Applications

This lecture covers the principles and applications of the Fabry-Perot standard, focusing on the operation of the device composed of two almost perfect mirrors with high reflectivity. It explains the spectral range, resolution, and intensity measurements, as well as the effects of misalignment and the stability of the cavity. The lecture also delves into the interference patterns, cavity modes, and the practical aspects of the Fabry-Perot standard, such as the use of dielectric mirrors and piezoelectric actuators for mirror movement. Additionally, it discusses the importance of cavity stability and the construction of 2D cavities for more complex patterns.
