Reduce Noise Automatically Between Optical Signals with DDPR
Direct Differential Phase Recovery for Optical Sensors
Tags: Australian National University, Australia, Electronics & Robotics, Industrial Automation & Manufacturing
The Direct Differential Phase Recovery (DDPR) algorithm offers real-time phase difference measurements between two optical signals, significantly reducing common noise issues without needing feedback control. It's designed for FPGA (Field-Programmable Gate Array) systems, providing a robust solution for weak and dynamic signal phase recovery, challenging for traditional phase-locked loops (PLLs). This technology finds applications in interferometric gyroscopes, laser ranging, and dispersion spectroscopy, improving reliability and noise suppression in optical measurements. DDPR demonstrates exceptional common mode suppression, essential for precise optical interferometry.
