The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it ...

Imaging objects that are partially or completely obscured by structures that diffuse the light from those objects, as is the case in many biological systems, is a challenge that engineers have met ...

Adaptive optics (AO) is a technique used for real-time correction of phase aberrations by employing feedback to adjust the optical system. Polarization aberrations represent another significant type ...

Quantitative phase imaging (QPI) is a cutting-edge optical technique that reveals variations in optical path length as light moves through biological samples, materials, and other transparent ...

A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of starlight suppression needed for future space observatories to pick out very ...
