High-speed three-dimensional (3D) surface imaging by structured-light profilometry is currently driven by numerous applications. However, the limited speeds in fringe pattern projection, image acquisition, and data transmission have strained the existing methods from reaching kilohertz-level acquisition, processing, and display of 3D information during the occurrence of dynamic events (i.e., in real time). To overcome these limitations, we have developed band-limited illumination profilometry (BLIP) with a CoaXPress interface (CI), which enables real-time high-speed 3D surface imaging. We have demonstrated the system's performance by imaging various static and fast-moving 3D objects in real time. We have also applied this system in fluid mechanics by imaging dynamics of a flag, which allowed observation of the wave propagation, gravity-induced phase mismatch, and asymmetric flapping motion. We expect CI-BLIP to find diverse scientific and industrial applications.

使用带CoaXPress界面的带限照明轮廓仪进行实时高速三维表面成像。

当前，由结构化光轮廓仪进行的高速三维（3D）表面成像是由众多应用程序驱动的。但是，条纹图案投影，图像获取和数据传输的速度有限，使现有方法在动态事件发生时（即实时）无法达到千赫兹级的3D信息获取，处理和显示。为了克服这些限制，我们开发了带有CoaXPress接口（CI）的带限照明轮廓仪（BLIP），该接口可实现实时高速3D表面成像。我们已经通过实时成像各种静态和快速移动的3D对象演示了系统的性能。我们还通过对标志的动力学进行成像，将该系统应用于流体力学，从而可以观察波的传播，重力引起的相位失配和不对称拍打运动。我们希望CI-BLIP能够找到多样化的科学和工业应用。
