In this article, we propose a laser feedback frequency-modulated continuous-wave (FMCW) ranging system based on multiple-equal-phase-subdivision (MEPS) resampling. An auxiliary interferometer is em…
Based on the Nd: YVO 4 microchip laser frequency-shifted feedback system, we carry out the detection of ultra-weak light signals, and verify that the response limit of the proposed system can reach…
A compact cantilever-based voice-eavesdropping microresonator is proposed. The dynamic vibration of the cantilever-microresonator system induced by an applied acoustic pressure is converted into a …
A novel temperature sensor based on rare earth fiber peanut (REFP) shape structure in fiber ring laser (FRL) is proposed and demonstrated. A single-mode rare earth doped fiber is used to fabricate …
