Lock-in Amplifiers

A lock-in amplifier is a specialized electronic instrument used to extract and measure small signals embedded in noise or interference. It is particularly useful in fields such as spectroscopy, photonics, communications, and materials science, where researchers need to measure weak signals against a background of noise.
