Lock in amplifier module. Lock in amplifiers were invented in the 1930 s 1 2 3 and commercialized in the mid 20th century as electrical instruments capable of extracting signal amplitudes and phases in extremely noisy environments see figure 1 they employ a homodyne detection scheme and low pass filtering to measure a signal s amplitude and phase relative to a periodic reference.

The high prices for usual desktop lock in amplifiers mean that they are not as common in noise limited experiments as would be desirable. Depending on the dynamic reserve of the instrument signals up to 1 million times smaller than noise components potentially fairly close by in frequency can still be reliably detected.
