contains a periodic structure, which causes spatially varying optical amplitude and/or phase changes.We have blazed holographic grating, concave grating, diffraction grating, holographic grating, ruled grating.
What is blazed grating?
When the grating is carved into a zigzag groove section, the light energy of the grating is concentrated in the predetermined direction, that is, at a certain spectral level. When you look in that direction, the spectrum is at its maximum intensity, and that's called a blaze.
