Other experiments suggest a particle model of light. An experiment is performed with the Fraunhofer pattern from a first mask impinging on a transparent second mask with a slit. The screen pattern is an interference pattern such as produced in Young’s Experiment. An opaque strip between the first and second mask blocks the light of the center maxima from the first mask. The screen interference fringes remained. Moving the glass mask so the slit is removed from light shows the necessity of a slit in the second mask. This suggests a Newtonian type of light model. This experiment rejects the wave models of light.展开更多

The influence of the dis- tance between the double-slit and the bucket detector preceded by a pinhole is studied. The experimental results show that the interference fringes become increasingly distinct with higher visibility when the pinhole-double-slit distance increases. A first-order classical theory based on the Klyshko＇s two-photon advanced-wave picture, and a second-order quantum-image theory are provided for explanations. The fitting results indicate that the divergence of the converted fluorescence significantly affects the ghost fringes.展开更多
