Boost Your Signal-to-Noise Ratio with Lock-in Detection

New technologies based on smaller and ever-more powerful devices often require precise measurements of tiny signals that are buried in noise. In this tutorial, you will learn how to use lock-in amplifiers and optimize measurement parameters to get the best signal-to-noise ratio. We will discuss three common use cases: optics and photonics experiments, material characterization, and resonator characterization. Finally, we will look at more advanced techniques, such as double modulation and multi-frequency measurements.
