An optical fiber in-line Mach-Zehnder interferometer based on a hollow ellipsoid fabricated by femtosecond laser micromachining and fusion-splicing technique is demonstrated. The surface of the hollow ellipsoid acts as an internal mirror that can be utilized for the construction of an interferometer. Such an interferometer device is miniature and robust and can perform external refractive index, curvature, and high-temperature sensing in a mutually independent way, and hence a simultaneous multiple parameter measurement capability can be readily achieved.
基于飞秒激光微加工和熔接技术制作的中空椭球的光纤在线马赫-曾德尔干涉仪得到了演示。中空椭球的表面充当内部反射镜，可用于干涉仪的构建。这种干涉仪装置小巧坚固，可独立对外界折射率、曲率和高温进行感测，因此可轻松实现同时进行多个参数的测量。
