Dual-Phase Lock-In Amplifier Based on FPGA for Low-Frequencies Experiments

Dual-Phase Lock-In Amplifier Based on FPGA for Low-Frequencies Experiments

Photothermal techniques allow the detection of characteristics of material without invading it. Researchers have developed hardware for some specific Phase and Amplitude detection (Lock-In Function) applications, eliminating space and unnecessary electronic functions, among others. This work shows t...
