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 ...

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 ...

The achromatic lens can focus the incident RCP and LCP light onto two distinct positions without chromatic aberration over a wide bandwidth. Broadband achromatic wavefront control, a cornerstone of ...
