Scattering of light as it passes through tissue is a significant barrier to imaging cleanly in biological media such as blood and skin. Wavefront shaping (WFS) is known to be a possible solution, in ...

Wavefront shaping is a promising approach to deep tissue imaging. Until now, it was possible only via an invasive approach: fluorescent points were manually inserted into the sample, and the tissue ...

Lithium niobate (LN) powers a newly developed optical metasurface for shaping and guiding light waves. Leveraging the electro-optical effect of lithium niobate, the device applies different electric ...

Researchers at Caltech make progress in medical imaging by adapting astronomical optics. A reflector shapes light waves to counterbalance distortion. Researchers in Caltech’s Andrew and Peggy Cherng ...
