Among existing_x000D_
technologies, the structured light (SL) 3D profilometry based on a digital micromirror device (DMD) has_x000D_
obtained increasing popularity owing to its flexibility and low cost. Despite the fast improvement in depth_x000D_
resolution and responding spectrum, the imaging and display speed of SL-based 3D profilometry has not kept_x000D_
pace, mainly due to two difficulties. First, current themes of single-shot sinusoidal fringe projection have_x000D_
residual noise and are subject to distortion induced by phase aberration. Second, the state-of-the-art high-speed_x000D_
cameras in existing SL-based 3D profilometers do not possess a sufficient data download speed._x000D_
Ajile Light Industries (ALI) is Canada's leading DMD-based 3D profilometry designing and manufacturing_x000D_
company. ALI has been seeking novel methods to increase the volumetric rate of their AjileWARE 3D camera_x000D_
to kHz levels. At 2016 SPIE's Photonics West conference, ALI established a collaboration with Prof. Liang on_x000D_
this topic. As an initial step to promote this university-industry partnership, this Engage application aims to_x000D_
develop an ultra-high-speed 3D profilometer capable of single-shot, precise sinusoidal pattern projection and_x000D_
real-time, continuous-streaming 3D imaging at kHz frame rates._x000D_
The proposed project comes in the auspicious confluence of talents. Prof. Liang's group has extensive_x000D_
research experience in imaging instrument designing, ultrafast 3D imaging, and DMD-based laser beam_x000D_
shaping. ALI will provide the 3D reconstruction software and their DMD controller system. The_x000D_
complementary expertise, fully covering the knowledge scope of the project, will ensure the successful and_x000D_
prompt completion of the proposed project. It is envisioned that the developed profilometer will open new_x000D_
avenues in both scientific research and industrial applications. The generated knowledge and technical_x000D_
know-how will assist in future product development and technology transfer., program purpose french : Three-dimensional (3D) optical metrology is of great importance to myriad applications. Among existing_x000D_
