Fiber interferometer
Experiment contents  and related  subjects:
Cutting and  end treatment of fiber.
Using the optical fiber as the transmission path of coherent light to assemble Mach-Zehnder interferometer and observe the interference fringes  through CCD.
Measure the impact on interference fringes caused by temperature change.
Features of the instrument:
Image acquisition throhgh CCD
Using semiconductor laser (650nm, 4mW) as the light source.
Using thermoelectric cooler for temperature adjustment and control ,the temperature control range is 10℃-40℃.
Complete set of  equipment
 Semiconductor laser, beam splitter, fiber coupler with seven degrees of freedom. CCD camera+ monitor, optical fiber, optical fiber cutter. Fiber stripping pliers, semiconductor temperature controller.
