The demand for optically reconstructing the three-dimensional (3D) surface shape of moving objects or deformation processes makes the development of high-speed projectors necessary. Our 3D sensor containing an array projector can achieve frame rates of several tens of kilohertz and is based on the projection of aperiodic sinusoidal fringes. This approach is compared with phase-shifting fringe projection as probably the most widely used technique. Theoretical considerations as well as extensive simulations are conducted to derive criteria for the design of optimal sequences of aperiodic sinusoidal fringes and to compare the number of patterns of both approaches necessary for comparable accuracies.
对光学重建移动物体的三维（3D）表面形状或变形过程的需求使得开发高速投影仪成为必要。我们的包含阵列投影仪的3D传感器可以实现几十千赫兹的帧率，并且基于非周期正弦条纹的投影。这种方法与可能是使用最广泛的相移条纹投影技术进行了比较。进行了理论考量以及广泛的模拟，以推导非周期正弦条纹最优序列设计的标准，并比较两种方法在可比精度下所需的图案数量。
