摘要： 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.
