Lock-in amplifiers are crucial instruments in research labs, especially in fields like optics, photonics, nanotechnology, quantum technologies, scanning probe microscopy, and sensing. These amplifiers excel at extracting small signals hidden in noise, making it possible to discover new scientific insights and enhance experimental setups. The lock-in amplifier operates on the principle of demodulation or phase-sensitive detection, which involves mixing the signal with a reference frequency and then applying a low-pass filter to isolate the desired information.
