Abstract

Optical sensing systems are increasingly required to deliver higher spatial resolution, faster acquisition rates, and improved 3D imaging capabilities. However, their performance remains constrained by fundamental physical limits, fabrication complexity, and cost. This work demonstrates how active optical elements combined with dedicated control strategies can significantly extend the capabilities of conventional imaging systems. First, focus-tuneable liquid lenses enable high-speed, inertia-free focusing with millisecond response times. This allows continuous focus stacking without mechanical motion, providing extended depth of field in high numerical aperture systems, post-acquisition focal plane selection, and depth reconstruction from image stacks. Second, the spatial resolution of image sensors — typically limited by pixel count, sensor size, and manufacturing yield — is enhanced using dynamic beam shifters. By introducing controlled sub-pixel lateral displacements and combining multiple acquisitions, the effective sampling density is increased.
