We further compared light-field sensors based on patterned nanocrystal arrays with conventional Shack–Hartmann sensors based on microlens arrays. The fabrication of nanocrystal light-field sensors is ...

Silicon is a common material of choice for semiconductor optics in the infrared spectral range, due to its low cost, well-developed high-volume manufacturing methods, high refractive index, and ...

People love the rainbow of ROYGBIV colors: red, orange, yellow, green, blue, indigo and violet. Human eyes perceive visible light as this array of colors. You may notice that some colors you can ...

Seven different vials are shown against a black background, each glowing a different color. From left to right, the vials are red, orange, yellow, green, blue, purple, and magenta. Quantum dots are ...
