  "abstract": "The present disclosure relates to relates to a system and method for measuring a real-time three dimensional shape using a diagonal fringe pattern. Particularly, in the deflectometry applied to real-time three dimensional shape measurement of freeform surfaces, a system for acquiring a real-time three dimensional phase using a diagonal fringe pattern includes: a pattern generation portion that generates a single-direction pattern in the diagonal direction and project the generated pattern onto a measurement object; a detector that obtains an image of a deformed pattern reflected from the measurement object; and a phase acquisition portion that partially differentiates and integrates a phase of the diagonal pattern in the x axis direction and y axis direction respectively, to obtain an x axis direction phase component and a y direction phase component.",
