Improvement of an Advanced Undergraduate Acoustics Laboratory

该项目将改进史密斯学院声学专业的高级本科教学和研究实验室。物理系将获得使用全息干涉计量术识别、演示和分析各种物体的振动模式的能力，从乐器开始。为了这个项目，史密斯将购买一个隔振光学工作台和底座、激振器、加速度计、数字快门、可变衰减器/分束器和空间滤光器。声学课程要求物理专业的学生进行为期一学期的实验项目，非专业的学生可以选择较短的项目。此外，声学实验室供从事荣誉和特殊研究项目的高年级学生使用。拥有使用全息干涉法识别振动模式的能力将为声学课程提供几个额外的实验室实验，并为专业学生提供另一种在实验项目中使用的技术。

This project will improve an advanced undergraduate teaching and research laboratory in Acoustics at Smith College. The Physics Department will acquire the capability to use holographic interferometry to identify, demonstrate, and analyze the vibrational modes of various objects, starting with musical instruments. For this project Smith will purchase a vibration isolated optical table and base, vibration exciter, accelerometer, digital shutter, variable attenuator/beam splitter, and spatial filter. The Acoustics course requires a semester-long experimental project from physics majors taking the course, and shorter projects may be elected by non-majors. In addition, the Acoustics laboratory is used by seniors doing Honors and Special Studies projects. Having the capability to use holographic interferometry in the identification of vibrational modes will provide several additional laboratory experiments for the Acoustics course as well as giving majors another technique for use in their experimental projects.
