Abstract: Provided is an image extraction method of optical phase extraction system. The image extraction method may include checking whether a phase error due to an environmental disturbance of optical fiber occurs by monitoring an output signal obtained by interfering reflection optical signals reflected through two paths. When a phase error occurs, an error is compensated using a phase compensation control method of closed loop type through one of the two paths and an image is extracted by capturing an image of object in a state that the image of object is shifted by the set phase value when a phase error is compensated. According to the inventive concept, a phase error occurring in an optical fiber type interferometer due to an environmental disturbance is minimized or compensated. Also, since an interference image accurately shifted by the phase value set among arbitrary various phase values is obtained through a camera, reliability of three-dimensional phase information being extracted is guaranteed.

Abstract: A fiber optic sensor head for detecting the shape or the distance of a test object has an optical fiber, in particular a glass fiber, for conducting and returning partial beams to and from the test object, and an injection/extraction lens on the test object side. For conducting partial beams, injected on the sensor head side and having an optical path length difference, to the test object and returning partial beams injected on the test object side without an optical path length difference, a Fizeau interferometer having a nondiscrete design is associated with the optical fiber and compensates for the optical path length difference between the partial beams.
