Interference Pattern to Hybrid Pattern to Diffraction Pattern --- Interaction Between Photons in Non-Parallel Two Slit Experiment

<p>The interference and the diffraction are two basic phenomena in physical optics. We have shown the phenomenon that, in the experiment of two slits with the certain angle between two slits, the partial interference pattern is embedded in the two diffraction patterns, namely, there is the partial interference + diffraction hybrid patterns.</p> <p>In this article, we show that the nature and the characteristics of the patterns depend not only on the distance from the diaphragm, but also on the angle between two slits. Namely, when the angle between two slits varies from 00 to 450, the pattern varies from the interference pattern to the hybrid patterns (i.e., the partial interference pattern embedded in diffraction patterns) to the diffraction patterns. Challenge is to interpret consistently the hybrid patterns.</p>
