Reflection amplitude diffraction gratings, that spatially and periodically modulates the intensity of an incident wave that is reflected from the grating. Transmission phase diffraction grating, that spatially and periodically modulates the phase of an incident wave passing though the grating. Zobraziť viac In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a … Zobraziť viac The wavelength dependence in the grating equation shows that the grating separates an incident polychromatic beam into its constituent wavelength components at different angles, … Zobraziť viac Diffraction gratings are often used in monochromators, spectrometers, lasers, wavelength division multiplexing devices, optical pulse compressing devices, and many other optical instruments.
