介绍了一种脉冲激光夹层全息术的新方法。互相夹在一起的两块全息干板放在一个特制的旋转的全息照相干板架内,激光器发射的双脉冲通过一个狭缝使干板曝光。双脉冲的间隔小于1毫秒。然后,在一个定位架上,让一块干板相对于另一块干板旋转,使二个脉冲所成的象重叠。随后把两块干板胶合。如果两块干板的乳胶面是分离的,那么只要在重现时,将夹层全息照片类似于物体作一倾斜(但比物体倾斜更大些),则由于在二个脉冲间物体倾斜所引起的条纹就能被消除。而倾斜的方向(向前或向后)在使用该方法时就会清楚。
A new method of pulsed laser sandwich holography is introduced. The two holographic plates, clamped to each other, are placed in a specially prepared rotating holographic plate rack, and the double pulse emitted by the laser exposes the plate through a slit. The interval between two pulses is less than 1 millisecond. Then, on a spacer, rotate a plate relative to the other plate so that the two pulses overlap. Then glue the two dry boards. If the latex planes of the two dry plates are separate, then as long as the sandwich hologram is tilted like an object (but larger than the object) at the time of reproduction, then due to the object tilting between the two pulses The stripes can be eliminated. The tilted direction (forward or backward) will be clear when using this method.
