《近场声全息测量分析系统的开发及应用》

近场声全息（NAH）已经成为国内学者的研究热点，并逐渐在工程实际中得到应用。但目前商业化的声全息系统成本高昂，从自身实际需求出发，开发经济适用的NAH系统很有必要。本文基于LabVIEW，采用以软件为核心的模块化设计，开发出了一套近场声全息测量分析系统。并应用该系统对边界约束的平板进行了实验研究。通过实验验证了该系统的实用性、可靠性。本文开发出的NAH系统为今后NAH的研究将提供良好的平台。

Development and Application of NAH Measurement and Analysis System

Near-field Acoustic Holography (NAH) has become a hot focus of researches at home and abroad. It has been gradually applied to practical engineer field. However, the existed commercial NAH systems are high expensive. So that , it is necessary to develop a economical and applicable system for NAH study. In this paper, a new NAH measurement &; analysis system base on LabVIEW is developed，which is designed modularly ,and of which software is the core. Also a boundary restricted plane experiment is conducted with this system. Practicability and reliability of this system is validated by the results. The system can provide a good platform for the NAH study in further.
