Bragg diffraction angle
WebJun 25, 2024 · Liquid-crystal polarization gratings (LCPGs) are attracting wide interests in both liquid-crystals and optics fields due to its intriguing formation process, unique optical properties, and potential applications in emergent wearable devices such as Augmented/Virtual Reality headsets. WebThe Bragg angle θ B is a very important concept in diffraction theory, e.g. widely used to explain electron and X-ray diffraction phenomena. Very strong intensities known as Bragg peaks are obtained in the diffraction pattern when scattered waves satisfy the Bragg condition. The angle between incident and reflected waves is equal to 2θ B as ...
