Sophisticated Double-Slit Interference Experiments Using Electron Waves

Electron double-slit experiments, the essence of quantum mechanical “wave/particle duality”, have been extensively and continuously studied because their unrealistic interpretations attracted many researchers. Here, we discuss recent sophisticated V-shaped experiments to elucidate electron-path information, i.e., which slit electrons pass through, path they pursue, where arrive interfere on image plane. In a transmission electron microscope, an optically zero-propagation distance condition was realized, position imaged just detector Interference fringes composed dot images were controlled by using two biprisms. Using double slit, confirmed that it is possible observe interference only when information individual not available. Furthermore, how would shift detected positions wave phases modulated before illumination slit. Phase shifts generated tilting beams. We each single as changed its phase even traveled alone inside microscope.
