当激光器以极短的脉冲工作时，传统的全息图像会变得严重退化，例如，在飞秒区域。我们描述的问题，并指出如何纠正产生退化的缺陷。通过使用变形光学器件和通道间耦合滤波器，点扩散函数的面积可以减小几个数量级。给出了实验结果。
Conventional holographic imagery can become severely degraded when the laser operates with extremely short pulses, e.g., in the femtosecond region. We describe the problems and indicate how to correct the defects producing the degradation. By the use of anamorphic optics and an interchannel coupling filter, the area of the point-spread function can be reduced by orders of magnitude. Experimental results are given.
