| Abstract Title: |
W09: Flexible, low-cost phase-sensitive detection with a Teensy microcontroller |
| Abstract: |
Phase-sensitive detection is widely used in experimental physics to recover a signal at a known reference frequency, particularly when there is a noise background. In this workshop, we describe how to use an inexpensive (<$30) Teensy microcontroller, which can be programmed like an Arduino, along with an open-source software package to perform phase-sensitive detection in the context of an undergraduate laboratory. Our platform provides a simple, accessible means to teach students about phase-sensitive detection. In addition, for some experiments, our system could be a viable alternative to a commercial lock-in amplifier. Participants in this workshop will be shown how to replicate our system at their own institution. |
