We demonstrate that it is possible to study the modal structures of a vibrating object with digitally recorded holograms by use of the time-averaging principle. We investigate the numerical reconstruction from a theoretical point of view, and we show that the numerically reconstructed object from a digital hologram is modulated by the zeroth-order Bessel function. Results of experiments in time-averaged digital holography are presented.
我们证明,利用时间平均原理,通过数字记录的全息图来研究振动物体的模态结构是可行的。我们从理论角度研究了数值重建,并表明从数字全息图进行数值重建的物体受到零阶贝塞尔函数的调制。文中给出了时间平均数字全息术的实验结果。
