A Modern DSP Based Lock-In Amplifier Designed for code and hardware experimentation By: Steven C. Hageman / AnalogHome Introduction Lock-In amplifiers have been around since their first development as described by Dicke in the 1940's[1] and they are still used today in many experimental systems. The technique is also called by a variety of names: Phase Sensitive Detection, Synchronous Detection and Narrow Band Detection. Figure 1 A typically challenging optical measurement. High attenuation of the optical Originally the technique was used to enable sample makes measuring the resulting light measurement on very small signals that would intensity difficult because of detector and otherwise be obscured by even the best available Amplifier noise.
