Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating’s surface. Diffraction Gratings can be either transmissive or reflective. As light transmits through or reflects off a Grating, the grooves cause the light to diffract, dispersing the light into its component wavelengths.
Gratings: Theory and Numeric Applications, AMU (PUP), , 2012, 978-2-8539-9860-4. The most important property of diffraction grating to create diffraction orders has been loss of a half of the incident light intensity requires twice the exposer time. Low polarization
The Diffraction Grating. After light passes through the slit, a set of lenses or mirrors collimates the light (makes all light rays parallel to the optical axis) and delivers the light to the diffraction grating. A diffraction grating consists of a material containing a periodic variation in one of its optical properties.

the grating normal, and θ’ is the angle of diffraction measured from the grating normal. The overall efficiency of the gratings depends on several application-specific parameters such as wavelength, polarization, and angle of incidence of the incoming light. The efficiency is also affected by the grating design parameters such as blaze

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
The most well-known applications are: 1- X-ray diffraction used in crystallography. 2- Diffraction Grating used to transform the light into its spectrum. 3- the most interesting application is the holography (you can check this amazing video https

Types Various techniques have existed for see-through HMDs.
Applications of Diffraction X-ray Crystalography The incoming beam (coming from upper left) causes each scatterer to re-radiate a small portion of its energy as a spherical wave. If scatterers are arranged symmetrically with a separation d, these spherical waves will be in synch (add constructively) only in directions where their path-length
Lasers are distinguished from other light sources by their coherence is typically expressed through the output being a narrow beam, which is beams can be focused to very tiny spots, achieving a very high irradiance, or they can have very low divergence in order to concentrate their power at a great distance.
