Technical Description

☑ Mach-Zehnder Interferometer Experiment

– Experiment Summary

The Mach-Zehnder Interferometer was originally designed primarily to meet the needs of precise optical measurements and to address the limitations of other interferometers in specific applications at that time.

Its experimental principle is based on the phenomenon of light interference, measuring the phase deviation between two collimated light beams. This phase deviation can be used to determine small displacements, transmitted wavefront errors of transmissive optical devices, refractive indices of transparent materials, air flow in wind tunnels, and so on.

It is widely used in fields such as physics, optics, and engineering, especially in precision measurement and sensing.

—— Experimental Principle:

The specific steps are as follows:

(1) Beam Splitting: An incident light beam is split into two optical paths by the first beam splitter.

(2) Optical Path Propagation: These two optical paths pass through their respective reflectors, are reflected, and continue to advance. Due to the different positions of the reflectors, the lengths of the two optical paths are usually different.

(3) Beam Recombination: At the second beam splitter, these two optical paths are recombined to form an interference pattern. If the optical path difference between the two light beams is an integer multiple of the wavelength, the interference will produce enhancement (constructive interference). If the optical path difference is an odd multiple of half the wavelength, the interference will produce weakening (destructive interference).

(4) Observation of Interference Pattern: The recombined light beam forms an interference pattern on the observation screen. By analyzing the position and changes of these interference fringes, information about the optical path difference can be obtained.

—— Experimental Objectives:

(1) Phase Measurement: Measure the phase change of light beams passing through different paths, which is very important for studying changes in the refractive index and thickness of materials.

(2) Interference Pattern Analysis: By observing and analyzing the interference pattern, the optical path difference can be accurately measured, which is applied to various precision measurements.

(3) Sensing and Detection: Used to detect small changes in physical quantities, such as temperature changes, pressure changes, vibrations, etc.

(4) Light Wavefront Analysis: Used to analyze wavefront distortion and correct optical systems.

(5) Basic Research: Widely used in basic research such as quantum mechanics and relativity experiments, optical imaging, and optical communication, such as quantum entanglement, counterfactual definiteness, quantum eraser experiments, and quantum Zeno effect.

(6) Flow Visualization: An ideal choice for observing gas flow in wind tunnels, commonly used in the fields of aerodynamics, plasma physics, and heat transfer to measure changes in gas pressure, density, and temperature.
