Superfast and large-depth-range sinusoidal fringe generation for multi-dimensional information sensing
文献摘要：
Among many multi-dimensional information sensing methods such as structured-light and single-pixel imaging technologies,sinusoidal fringe generation is general and crucial.Current methods of sinusoidal fringe generation force concessions in either the speed or the depth range.To mitigate this trade-off,we have simultaneously achieved both speed breakthrough and depth range enhancement by improving both the optical projection sys-tem and binary coding algorithm based on an off-the-shelf projector.Specifically,we propose a multifocal pro-jection system and oblique projection method,which essentially eliminates the existence of a single focal plane in the conventional axisymmetric system and utilizes its anisotropy characteristics to achieve a superior filtering effect.Furthermore,the optimal pulse width modulation technique is introduced to modulate the square binary pattern for eliminating specific harmonics.To the best of our knowledge,the proposed method,for the first time,simultaneously achieved superfast(9524 frames per second)and large-depth-range(560 mm,about three times that of the conventional method)sinusoidal fringe generation with consistently high accuracy.Experimental re-sults demonstrate the superior performance of the proposed method in multi-dimensional information sensing such as 3D,4D,and[x,y,z,t;s(strain)].
