Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: Disclosed are methods for imaging lumen-forming structures such as blood vessels using near-infrared fluorescence in the NIR-II region of 1000-1700 nm. The fluorescence is created by excitation of solubilized nano-structures that are delivered to the structures, such as carbon nanotubes, quantum dots or organic molecular fluorophores attached to hydrophilic polymers. These nanostructures fluoresce in the NIR-II region when illuminated through the skin and tissues. Fine anatomical vessel resolution down to ?30 ?m and high temporal resolution up to 5-10 frames per second is obtained for small-vessel imaging with up to 1 cm penetration depth in mouse hind limb, which compares favorably to tomographic imaging modalities such as CT and MRI with much higher spatial and temporal resolution, and compares favorably to scanning microscopic imaging techniques with much deeper penetration.
