我们演示了光脉冲在玻璃块内的折射和全折射以及在光栅处的衍射。用皮秒脉冲激光记录全息图，可以观察光传播的无框连续运动图像。结果表明，由于折射作用，脉冲的方向发生了变化，脉冲在玻璃块中的传播速度降低，脉冲在玻璃块中的传播路径呈锯齿形。衍射光平行于光栅面传播的脉冲波前也被证明。(C)2002年美国光学学会。
We demonstrate the propagation of a light pulse undergoing refraction and total refraction inside a glass block as well as diffraction at a grating. Observation of a frameless, continuous motion picture of the light propagation is possible by recording of hologram with a picosecond pulsed laser. It is shown that the direction of the pulse changes as a result of refraction, the pulse's speed decreases inside a glass block, and the pulse travels a zigzag path by total refraction. The pulse fronts of the diffracted light propagating parallel to the grating surface are also demonstrated. (C) 2002 Optical Society of America.
