چکیده
We report on the construction and characterization of a low-cost Mach–Zehnder optical interferometer in which quadrature signal detection is achieved by means polarization control. The device incorporates generic green laser pointer, home-built photodetectors, 3D-printed mounts, circular polarizer extracted from pair 3D movie glasses, python-enabled microcontroller for analog-to-digital data acquisition. Components fit inside [Formula: see text] space can be assembled budget less than US$500. has potential to make interferometry accessible affordable instructors, students, enthusiasts alike.

Quadrature Mach–Zehnder interferometer with application in optical coherence tomography
A novel quadrature interferometer based on Mach–Zehnder configuration and a 3 × 3 fibre coupler is presented. Measurements showing instantaneous extraction of both real and complex parts of the interferometric signal are described. The features of this quadrature interferometric platform are discussed with a focus on signal-to-noise ratio and optical power handling.
متن کاملImaging through turbulence with a quadrature-phase optical interferometer.
We present an improved technique for imaging through turbulence at visible wavelengths using a rotation shearing pupil-plane interferometer, intended for astronomical and terrestrial imaging applications. While previous astronomical rotation shearing interferometers have made only visibility modulus measurements, this interferometer makes four simultaneous measurements on each interferometric b...

introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...
متن کاملA Homodyne Quadrature Laser Interferometer for Micro-Asperity Deformation Analysis
We report on the successful realization of a contactless, non-perturbing, displacement-measuring system for characterizing the surface roughness of polymer materials used in tribological applications. A single, time-dependent, scalar value, dubbed the collective micro-asperity deformation, is extracted from the normal-displacement measurements of normally loaded polymer samples. The displacemen...
