核心研究进展(Core Research Progress

传统扫描三维测量难以兼顾高精度、大量程与高速检测。该研究提出基于啁啾光频梳(Chirped Optical Frequency Comb)的无扫描三维测量(No-scanning 3D Measurement)方案,依托光谱干涉(Spectral Interferometry)技术实现超快维度转换、单次成像重建。可同时实现480μm微观微米级检测与3米大尺寸高精度测量,有效解决传统测量精度与量程无法兼容的痛点。

 

技术应用价值(Technical Application Value

该技术无需机械扫描,具备超快成像、微米级高精度、超宽动态量程等优势,支持微观、大尺寸、大纵横比等多尺度三维检测。适用于超快动态成像与工业精密测量场景,为通用型高性能三维感知技术产业化提供有力支撑。
