The optical signals of the three LISA interferometers (long-arm, reference, and test-mass) on each optical bench are detected by opto-electronic devices named Quadrant Photoreceivers (QPRs). Each QPR features three main components: (1) an InGaAs quadrant photodiode (QPD) with four segments; (2) front-end electronics (FEE) incorporating a...
