论文摘要
我们报告了低成本马赫德光学干涉仪的构建和表征,其中通过极化控制实现了正交信号检测。该设备结合了通用的绿色激光指针,家庭制造的光电电视器,3D打印的光学支架,从一对3D电影眼镜中提取的圆形偏振器以及一个启用Python的微控制器,以进行模拟数据采集。组件适合12“ x6”空间内部,并且可以以低于500美元的预算组装。该设备有可能使教师,学生和爱好者都可以访问正交干涉法和负担得起。
We report on the construction and characterization of a low-cost Mach-Zehnder optical interferometer in which quadrature signal detection is achieved by means of polarization control. The device incorporates a generic green laser pointer, home-built photodetectors, 3D-printed optical mounts, a circular polarizer extracted from a pair of 3D movie glasses, and a Python-enabled microcontroller for analog-to-digital data acquisition. Components fit inside of a 12"x6" space and can be assembled on a budget of less than US\$500. The device has the potential to make quadrature interferometry accessible and affordable for instructors, students, and enthusiasts alike.
