How to substantially reduce encoder cost while gaining functionality with 44-Turn multi-turn rotary position sensors—retaining count and position during power loss.
Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...
Figures of merit for single-photon detectors. The most widely quoted figure of merit for photodetectors is the noise equivalent power (NEP)24, and this has proved useful for optical power measurements ...
