A wavefront sensor is a device for measuring an optical wavefront and any aberrations within it. The wavefront is a region in which all the points sampled in the wave have the same phase at a given instant.
In a pre-proof article posted in Optics Communications, researchers proposed a novel angle-of-arrival (AoA) tracking device that eliminates the need for beacon lights and beam splitters by employing an integrated beam alignment positioning sensor with a data photo-detector (PD).
A pre-proof study from Optics Communications introduces a microscopic image fusion technique to improve the signal-to-noise ratio, the dynamic range, and the root-mean-square contrast of dark-field confocal microscopy imaging. This method generates high-quality images with uniform brightness and improves the damage threshold of optical systems.
In a pre-proof study from the journal Optics Communications, the researchers present a method for generating linearly frequency swept optical waves using a digital optical phase-locked loop (OPLL).
An Optics Communications pre-proof study proposed a novel optical refractive index sensor design based on electromagnetic multipolar quasi-bound states in the continuum (BICs) to enhance its figure of merit (FOM). This creates opportunities for ultra-high FOM optical refractive index sensing with high sensitivity.
