Market Study of CoaXPress-Interfaced Band-Limited Illumination Profilometry (CI-BLIP)

高速三维（3D）表面成像的结构光轮廓术目前是由工业需求，医疗应用和娱乐驱动的。根据市场研究未来分析，到2023年底，全球3D成像市场的价值约为360亿美元。在2017年至2023年的预测期内，复合年增长率为28%。然而，条纹图案投影、图像采集和数据传输的有限速度使现有方法在动态事件（即实时）发生时无法达到千赫兹（kHz）级的3D信息采集、处理和显示。为了克服这些限制，我们开发了coaxpress接口带限制照明轮廓术（CI-BLIP），它可以在1khz下实现实时3D表面信息重建。我们通过对各种静态和快速移动的3D物体进行实时成像，展示了该系统的性能。我们还将该系统应用于流体力学中，通过对旗子的成像动力学，可以观察到波的传播、重力引起的相位不匹配和不对称的扑动。与现有的基于二元离焦和离线传输的结构光照明的三维成像系统相比，CI-BLIP具有系统操作方便、实时响应速度快、易于系统小型化等优点。我们希望CI-BLIP能够找到各种科学和工业应用。在这方面，这项NSERC I2I市场研究将有助于确定最有前途的应用，分析潜在市场的前景，并促进从实验室到产品的技术转移。

High-speed three-dimensional (3D) surface imaging by structured-light profilometry is currently driven by industrial needs, medical applications, and entertainment. According to Market Research Future Analysis, the global 3D imaging market has been valued at approximately USD 36 Billion by the end of 2023 with approx. 28% of a compound annual growth rate during the forecast period from 2017 to 2023. However, the limited speeds in fringe pattern projection, image acquisition, and data transmission have strained the existing methods from reaching kilohertz (kHz)-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 CoaXPress-interfaced band-limited illumination profilometry (CI-BLIP), which enables real-time 3D surface information reconstruction at 1 kHz. 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. Compared with the existing 3D imaging systems based on structured-light illumination by using binary defocusing and off-line transmission, CI-BLIP has the advantages in the convenient system operation, the high-speed real-time response, and the easier system miniaturization. We expect CI-BLIP to find diverse scientific and industrial applications. In this regard, this NSERC I2I Market Study will assist in identifying the most promising applications, analyzing the prospect of the potential market, and facilitating technology transfer from the laboratory to the product.
