The method has been successfully used in the system for measuring the 3-D surface topography of diffractive optical elements. 此方法已成功地應用於自行研製的衍射光學元件三維表面形貌測量系統中。
The progress situations of Optical 3D shape measurement technique are presented in this paper, especially Grating Projection Profilometry and Digital Holography Profilometry. 本文對現階段被廣泛採用的光學三維形貌測量技術的發展現狀進行詳細介紹，重點分析現已應用在三維形貌測量中的光柵投影技術和數字全息技術。
