Robert Hanbury Brown is known for developing the intensity type of this instrument. The Fabry-Perot type uses a pair of parallel half-silvered glass plates, one of which is adjustable, while an acoustic version can be used to measure the velocity and absorption of sound waves in a gas or liquid. Identify this device that splits electromagnetic radiation into two parts, used in radio astronomy and which was, FTP, essential to the Michelson-Morley experiment.
