Mastering Periodic Signal Analysis for Optics & Photonics Applications

Optics and photonics research aims to measure increasingly smaller effects and faster processes. For a wide range of specific applications, the signals stemming from such experiments are tiny and often buried in noise or covered by large backgrounds.

By averaging only the signal of interest while simultaneously rejecting all spurious noise contributions, Lock-in amplifiers, and boxcar averagers are the ideal tools to boost your signal-to-noise ratio when measuring small optical signals.

In this webinar, we discussed:

• The measurement principles of lock-in amplification and boxcar averaging;
• Why such techniques are beneficial for capturing small signals in optical experiments and
• The applications benefitting from the two different approaches.
