Researchers in Caltech's Andrew and Peggy Cherng Department of Medical Engineering have made a major step forward in medical imaging by taking inspiration from the field of astronomy. The paper ...

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 ...

Engineers from Rice University and the University of Maryland have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky ...

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 ...

Wavefront shaping has emerged as a transformative approach to overcome the inherent limitations of imaging through turbid or scattering media. In such environments, inhomogeneities deflect and ...

The ability of simultaneous polarization filter and wavefront shaping is very important for many applications, especially for polarization imaging. However, traditional methods rely on complex ...

(a) Schematic illustration of the proposed signal modulation process. Left: initial input laser spot illustration before interacting with the SLM and Si metasurface. Middle: schematic of the linear ...

Researchers find new way to measure small distortions in light waves through 'quasiparticles.' This new technique advances applications in metrology and chemical sensing, and improves adaptive optics ...

Researchers have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating.

Venture-backed French startup company Keranova says that its femtosecond laser system will "revolutionize" the field of cataract operations, by providing surgeons with a single tool that can be used ...

Scattering-Assisted Localization Microscopy (SALM) is a super-resolution microscopy tool where high resolution is obtained based on the size of the grain in the speckle pattern on the sample. The ...
