Diffraction efficiency
Diffraction efficiency is the performance of diffractive optical elements – especially diffraction gratings – in terms of power throughput. It s a measure of how much optical power is diffracted into a designated direction compared to the power incident onto the diffractive element. If the diffracted…

Equation for diffraction grating
Reflection Diffraction Gratings (not on the syllabus!) Transmission Diffraction Gratings A transmission diffraction grating is a slide with large number of parallel, closely spaced slits (transparent spaces) drawn on it. Early ones were carbon covered glass slides etched by a needle point - now they tend to be printed onto a slide. When a parallel beam of monochromatic light is…

When viewing a photograph, we imply a third dimension based upon our past perceptions of similar situations. Holograms are 3 or 4 dimensional. Height, width, depth, and motion(time), are all recorded in a holograph. But, the theory of holography is what is…
