Popis:	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. Comment: 11 pages, 7 figures
