Furthermore, this physical image denoising framework was experimentally demonstrated using terahertz radiation and a 3D-fabricated diffractive denoiser. This all-optical image denoising framework ...

In Light: Science & Applications journal UCLA researchers introduce an innovative design for diffractive deep neural networks (D 2 NNs). This new architecture, termed Pyramid-D 2 NN (P-D 2 NN), ...

Spatially incoherent diffractive optical processors can handle data beyond non-negative values, potentially making them valuable in diverse scenarios, such as visual encryption and autonomous vehicle ...

Now you see it: A schematic of the experiment, in which an optical diffractive camera hides information by concealing it within ordinary-looking “dummy” patterns. (Courtesy: A Ozcan) Information ...

A depth-compensated diffractive optical element photoacoustic microscope enables more uniform photoacoustic imaging across tissue depths.

Figure | Artistic depiction of a diffractive optical processor for massively parallel and universal approximation of nonlinear functions. Input variables are encoded into the phase of a light wave, ...

(Nanowerk Spotlight) In the age of big data, we are generating more images than we can actually process. Autonomous vehicles, medical scanners, and quality control systems rely heavily on ...

Privacy is an apparent problem with cameras incorporated into everything from smartphones to wearables to smart glasses. Researchers intend to emphasize privacy by ...
