Quantum theory of light diffraction

TL;DR

This paper develops a relativistic quantum theory of light diffraction, explaining effects like slit thickness influence that wave optics cannot, and validates the theory with experimental data.

Contribution

It introduces a quantum relativistic approach to light diffraction, providing explanations for phenomena unaccounted for by traditional wave optics.

Findings

Diffraction intensity depends on slit dimensions and wavelength.

Slit thickness effects are explained by quantum theory, not wave optics.

Theoretical results agree with experimental data.

Abstract

At present, the theory of light diffraction only has the simple wave-optical approach. In this paper, we study light diffraction with the approach of relativistic quantum theory. We find that the slit length, slit width, slit thickness and wave-length of light have affected to the diffraction intensity and form of diffraction pattern. However, the effect of slit thickness on the diffraction pattern can not be explained by wave-optical approach, and it can be explained in quantum theory. We compare the theoretical results with single and multiple slits experiment data, and find the theoretical results are accordance with the experiment data. Otherwise, we give some theory prediction. We think all the new prediction will be tested by the light diffraction experiment.
