For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could change with a revolutionary new measurement method, devised by AMOLF researchers Kevin Peters and Said Rodriguez. Their idea is based on a non-linear optical resonator, explains Rodriguez: “In this sensor, faster measurement actually produces a stronger signal.” The theoretical elaboration of this new measurement method is published in Physical Review Letters today, June 27, 2022. For an experimental exploration, collaborations are being sought with companies seeking to make fast and precise measurements with light.
