A comprehensive polarization double-slit interference optical experiment device, method and system

Abstract

The present application relates to the field of optical technology, particularly to a comprehensive polarization double-slit interference optical experiment device, method and system. The present application designs a new type of orthogonal polarization double-slit, which is covered with linear polarization films with mutually perpendicular optical transmission axes in front of the two slits, so that the light beams passing through the two slits become linearly polarized light with orthogonal polarization directions. When the polarization angle of the polarizer is not parallel to the polarization direction of any polarization film in the orthogonal polarization double-slit, the Young's interference fringes cannot be observed on the optical sensor, thereby directly showing the particle representation of light. By adjusting the polarization angle of the polarizer, the two light beams can regain coherence, and the Young's interference fringes can be reproduced on the optical sensor, thereby showing the dynamic conversion between the particle phenomenon and the wave phenomenon of light. The present application fills the gap that the existing experimental instruments cannot demonstrate the wave-particle duality phenomenon of light at the quantum level, and can enrich the current physics teaching practice content.
