Class Information
Number: 356/519
Name: Optics: measuring and testing > By light interference (e.g., interferometer) > Having partially reflecting plates in series (e.g., fabry-perot type)
Description: Measuring and testing by light interference wherein the beams to be interfered are created by at least two surfaces in optical alignment, at least one of which is partially transmissive, so as to form a resonant cavity.
