High-frequency dual-channel lock-in detection via rapidly oscillating driving
Kangze Li, Xu Zhao, Liantuan Xiao +1
Here we propose a general protocol for dual-channel lock-in detection of high-frequency ac signals. We find that the effect of a high-frequency target signal can be modulated throu…
High-sensitivity and high-resolution collaborative determination of birefringence coefficient using weak measurement
Shuqi Gao, Min Zhang, Jiahui Hou +5
Precise nanofilm birefringence characterization is essential for high-sensitivity polarization response and strong anti-interference detection in photodetectors. We present a high-…
