diffraktsioonigradi
Diffraktsioonigradi, often shortened to diffractive grating, is an optical component with a periodic structure that divides and diffracts light into several beams travelling in different directions. The angle of diffraction is determined by the wavelength of the incident light and the spacing of the grating. This phenomenon is a result of the interference of light waves scattered from the periodic structure. Diffractive gratings are typically made by etching a series of fine parallel lines or grooves into a transparent or reflective surface.
The principle behind a diffractive grating's operation is Huygens' principle, which states that every point on
The spacing between the grating elements, known as the grating period, is a crucial parameter. A smaller
