实验证明了四个晶体的级联锥形衍射现象。不到一年前，M.V. Berry预测，N晶体级联的锥形衍射焦点图案是2N− 1个单晶同心锥形衍射图案（环）的叠加，其环半径是级联中单个晶体的半径的组合。这里提出的实验观察结果与这些理论预测完全一致。
The cascade conical diffraction phenomenon from up to four crystals is experimentally demonstrated. Less than one year ago M.V. Berry predicted that the focus pattern of conical diffraction from anN-crystal cascade is the superposition of 2N−1single-crystal concentric conical diffraction patterns (rings), whose ring radii are a combination of those from the individual crystals in cascade. The experimental observations presented here are in full agreement with these theoretical predictions.
