This paper presents an approach based on a laser interferometer set-up to perform an experimental study of Hooke’s law for the case of the bending of a cantilever beam. We used weights and a pulley to deform the beam laterally and measured displacement with an electronic speckle pattern interferometer (ESPI). The ESPI set-up was built using items commonly found in an undergraduate optics laboratory and the software used for the measurement as presented in this paper is available for anyone to use. This represents an attempt at content development with an ESPI; development of various types of content with ESPIs can broaden the horizons of higher education and enhance classroom environments.

使用电子散斑图案干涉术的胡克定律实验

本文介绍了一种基于激光干涉仪设置的方法，可以对悬臂梁弯曲情况下的胡克定律进行实验研究。我们使用砝码和滑轮使光束横向变形，并使用电子散斑图案干涉仪（ESPI）测量位移。ESPI设置是使用本科光学实验室中常见的项目构建的，本文中介绍的用于测量的软件可供任何人使用。这表示使用ESPI进行内容开发的尝试；使用ESPI开发各种类型的内容可以拓宽高等教育的视野并改善教室环境。
