提出一种激光片光三维传感中降低散斑影响的新方法：片光面内扫描合成孔径法。通过向被测物体表面投射面内扫描的片状激光束，产生空间变化的动态散斑光场，这样的光场在成像透镜光瞳平面上的移动，其时间平均效果等效于利用了一个大的“合成孔径”，降低了散斑的影响，明显地提高了测量精度。文中给出了合成孔径的理论分析和三维面形测量的实验结果
A new method to reduce the influence of speckle in laser three-dimensional light sensing is proposed: slice smooth inner scanning synthetic aperture method. By projecting the in-plane scanning flaky laser beam onto the surface of the object, a spatially varying dynamic speckle light field is generated. Such a light field moves in the pupil plane of the imaging lens. The time-average effect is equivalent to using a Large “synthetic aperture”, reducing the impact of speckle, significantly improve the measurement accuracy. In this paper, the theoretical analysis of synthetic aperture and the experimental results of three-dimensional surface measurement are given
