This work presents a novel concept for 2D Scheimpflug lidar. A light-sheet based 2D Scheimpflug lidar system is developed and realized for surface profile measurements. The theory of a geometrical relationship underlying the system is developed, and the possibility of 3D profile measurements for a plastic bowl, a rhombic carton box and a manikin are presented. The sizes of reconstructed images are consistent with respective physical objects with small (~mm) errors at close range. Experimental results show that the 2D Scheimpflug lidar system performs well for 3D surface profiling and has great potential for close-range applications in other fields.
