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.
