Optics diffraction

WebThis is a general property of interference and diffraction: a known wavelength of light can be used to probe the size of a structure or the known dimensions of a diffracting object (in this case the width of the slit) can be used to deduce the wavelength of incident light. We will employ both techniques to make diffraction-based measurements. WebAug 2, 2024 · A retroreflective grating with a high line density is one of the most desirable optical elements, as it is capable of channeling the reflected light toward the source with high angular resolution. Metagratings can steer the incident light into the desired diffraction order with ultrahigh deflection angle and unitary efficiency. However, in practice, the …
