Combining TV holography recording with acoustic phase stepping and image processing, we measure the integrated density distribution in sound fields that propagate in air. We record a given number of two-dimensional cross sections that are tomographically backprojected to give the amplitude and phase distributions of the emitted sound field. The validity of the procedure is demonstrated.
将电视全息记录与声学相移和图像处理相结合，我们测量了在空气中传播的声场中的综合密度分布。我们记录给定数量的二维横截面，对其进行断层反投影以得到发射声场的幅度和相位分布。证明了该方法的有效性。
