| 摘 要： | 三维传感系统中，二元误差扩散编码光栅可应用于产生质量较好的正弦结构光场．针对光场对比度下降问题，本文提出一种改善方法．计算机仿真实验表明，系统点扩散函数为椭圆对称高斯函数时，应用二元误差扩散编码光栅可得到对比度较强正弦光场，PMP系统抗干扰性增强．

| Abstract: | Binary Error Diffusion Gratings can be used in Three-dimensional(3-D) sensing systems in order to obtain sinusoidal structure illumination with good quality.Aiming at the problem of light field contrast reduction,we bring forward a method.Computer simulation shows that if the system point spread function is the elliptic symmetry Gussian function,sinusoidal structure light field with high constrast can be obtained,so the noise immunity of the system is approved. |
