    • PURPOSE: Device and method for measuring the angular displacement of an object with an interferometer are provided to reduce weight of a rotary interferometer and increase a range of angle. CONSTITUTION: A device for measuring the angular displacement of an object with an interferometer comprises a laser beam generator(100) and a splitter. The splitter splits the laser beam to a reference beam and a measuring beam. The reference beam directs to a fixed reference retro-reflector and subsequently, a phase shift detector(200). The measuring beam directs to the rotatable reflecting surface of the object and a fixed measuring retro-reflector, returns to the rotatable reflecting surface and directs to the phase shift detector. As a result, the phase shift detector measures the angular displacement of the rotatable reflecting surface when the path length of the measuring beam changes, when the rotatable reflecting surface makes displacement.
    • 目的:提供用于通过干涉仪测量物体的角位移的装置和方法,以减少旋转干涉仪的重量并增加角度范围。 构成:用于用干涉仪测量物体的角位移的装置包括激光束发生器(100)和分离器。 分束器将激光束分成参考光束和测量光束。 参考光束指向固定的参考反射器,随后指向相移检测器(200)。 测量光束指向物体的可旋转反射表面和固定的测量后向反射器,返回到可旋转反射表面并引导到相移检测器。 结果,当可旋转反射表面发生位移时,相移检测器测量当测量光束的路径长度改变时可旋转反射表面的角位移。

    • In accordance with the invention, an improved optical assembly having a monolithic structure is provided. The monolithic optical assembly is useful in interferometers to achieve a fringe effect in a Fourier transform spectrometer, and comprises top and bottom members which are joined into a monolithic structure by first and second support members and a beamsplitter. The assembly also comprising a first reflecting assembly in reflecting relation with the beamsplitter. An alternate embodiment of the invention has an added reflecting assembly in reflecting relation with the first reflecting assembly and the beamsplitter assembly, which allows for the use of multiple wavelength light sources to achieve a fringe effect in a Fourier transform spectrometer.
