Importantly — and unlike a physical grating — the properties of an acoustic-optic grating, such as its pitch and strength, can be controlled by altering the frequency, polarization and ...

Each Wasatch Photonics volume phase holographic (VPH) grating produced is an original, with consistent performance from one grating to the next. Our proprietary processes minimize stress, resulting in ...

Plymouth Grating Laboratory has established the first commercial production system using Scanning Beam Interference Lithography (SBIL) to manufacture gratings and Nanoruled surface structures that can ...

Fiber Bragg gratings are used to turn an optical fiber into a sensing element by reflecting a specific wavelength back in the direction from which it came. New dissolvable fiber Bragg gratings can ...

However, existing VTSs primarily rely on geometric optics or marker tracking technology ... structural color patterns formed by the flexible grating films under LED white light illumination ...
