The color liquid crystal grating has three different pitch regions in one liquid crystal cell, corresponding to incident light with different wavelengths, respectively. Additionally, a chromatic ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Holographic 3D display completely avoids the side effects of the traditional 3D display, such as the dizziness and fatigue of viewers. Therefore, it has become the frontier and hotspot of the current ...

Holographic display technology provides an ultimate solution for real 3D display and has great potential in augmented reality and virtual reality. However, the color and viewing angle of holographic ...
