Optical clearing of tissue has enabled optical imaging deeper into tissue due to significantly reduced light scattering. Here, Ryan et al. tackle first-order defocus, an artefact of a non-uniform refractive index, extending light-sheet microscopy to partially cleared samples. Duncan P. Ryan , Eliz...

We use optical feedback based wave-front shaping to transform the speckle pattern behind a scattering layer into a light sheet within the region of interest. Hence, the setup employs three objective lenses: one objective lens for illumination; a second one facing the first on the opposite side...

these new opal films have a small contrast in their optical properties. As with other artificial opal structures, they are also "self-assembling," in that the small constituent particles assemble themselves in a regular structure. But this self-assembly is not perfect, and though meant to be ...
After the fabrication, electrical and optical simulations were performed. Substrate and source contacts were biased to 0 V, and the gate voltage was −5 V. The drain voltage was varied from 0 V to 5 V. The light source was modeled using a uniform beam with wavelength (λ) of 600 nm ...
The very low values of the RMSE indicate a very small deviation from the residual ground truth. Thus, the accuracy of the model is very high for all of the four cases that were studied. When comparing these results to the results of other works concerning optical wireless positioning systems...
While there is clear evidence that simple optical instruments such as plane and curvedmirrorsand convexlenseswere used by a number of early civilizations,ancient Greekphilosophers are generally credited with the first formal speculations about the nature of light.
