摘要

通过搭建反射式 V 型纹影光路，实现了 40 kHz 超声波的可视化。利用该纹影光路设计了一系列关于声学内容的教学实验。这些内容可以直观、方便地对声学行波场的反射、衍射、准直以及一维、二维声学驻波场的力学效应进行演示探究，也可以对声场及声学器件的相关参数进行定量测量。这些实验结合了光学、声学、力学等学科内容，同时融入学科前沿应用，丰富了目前大学物理实验中传统声学实验的内容。

Abstract:

By designing and building a reflective V-schlieren light path ,the visualization of 40 kHz sound waveis realized.Using the schlieren light path,a series of teaching experiments about acoustics are designed anddeveloped.These contents can directly and conveniently demonstrate the reflection , diffraction , collimation ofhe acoustic traveling wave field and the mechanical effects of the one-dimensional and two-dimensionaacoustic standing wave field,and can also quantitatively measure the relevant parameters of the acoustic fieldand acoustic devices.The design and development of some experimental contents combines optics, acoustics. mechanics and other contents , and integrates the frontier application of acoustics, which greatly expands andenriches the contents of traditional acoustic experiments in current university physics experiments.

Key words: schlieren optics sound velocity measurement fresnel ultrasonic lens acoustic lattice acoustic levitation
