Three-dimensional (3D) optical metrology is of great importance to myriad applications. Among existingx000D
technologies, the structured light (SL) 3D profilometry based on a digital micromirror device (DMD) hasx000D
obtained increasing popularity owing to its flexibility and low cost. Despite the fast improvement in depthx000D
resolution and responding spectrum, the imaging and display speed of SL-based 3D profilometry has not keptx000D
pace, mainly due to two difficulties. First, current themes of single-shot sinusoidal fringe projection havex000D
residual noise and are subject to distortion induced by phase aberration. Second, the state-of-the-art high-speedx000D
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 manufacturingx000D
company. ALI has been seeking novel methods to increase the volumetric rate of their AjileWARE 3D camerax000D
to kHz levels. At 2016 SPIE's Photonics West conference, ALI established a collaboration with Prof. Liang onx000D
this topic. As an initial step to promote this university-industry partnership, this Engage application aims tox000D
develop an ultra-high-speed 3D profilometer capable of single-shot, precise sinusoidal pattern projection andx000D
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 extensivex000D
research experience in imaging instrument designing, ultrafast 3D imaging, and DMD-based laser beamx000D
shaping. ALI will provide the 3D reconstruction software and their DMD controller system. Thex000D
complementary expertise, fully covering the knowledge scope of the project, will ensure the successful andx000D
prompt completion of the proposed project. It is envisioned that the developed profilometer will open newx000D
avenues in both scientific research and industrial applications. The generated knowledge and technicalx000D
know-how will assist in future product development and technology transfer.
