Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight phenomenon, consisting of a LASER at source and detector at …

Michelson proposed an interferometric apparatus in 1890 following an earlier suggestion by Fizeau. The invention became the precursor of many important modern optic measurement techniques. The Michelson Interferometer, as it is called, is used to measure small optical path length changes. The classic Michelson Interferometer consists of two mirrors (one forming …
