摘要：
We describe a method for lock-in amplification that uses a chaotic reference signal and a synchronized receiver. This technique is compared with conventional lock-in methods using a periodic reference signal. The apparatus can be constructed in an undergraduate electronics lab using a light emitting diode for the transmitter and a photodiode for the receiver, and allows students to explore a novel measurement technique based on chaotic dynamics.
