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

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 ...

(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 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 ...

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 ...

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 ...

Analytical modeling is used to estimate coating-contributed transmitted wavefront error in precision optical coatings.
