Video-rate multi-scale band-limited illumination profilometry with cubic-meter-level measurement volume

We have developed multi-scale band-limited illumination profilometry (MS-BLIP), for robust video-rate three-dimensional (3D) imaging over measurement volumes at the cubic meter (m$^{3}$) level. MS-BLIP applies a newly developed iterative method for distortion compensation, which empowers a dynamic 3D visualization with a measurement volume of up to 1.5 m$^{3}$. It can robustly resolve spatially isolated objects with varied reflectance. It also allows flexible adjustment of the orientation of the field of view with a dove prism. MSBLIP showcases the video-rate 3D surface imaging of full human-body movements.
