摘要：
Considering prior statistical information about multi-scale of a target scene, a multi-scale ghost imaging LiDAR via sparsity constraints using push-broom scanning is proposed in this work. This method significantly improves the imaging efficiency. Simulation and experimental results demonstrate that it has higher imaging quality at low sampling rate than using single-scale speckle pattern.
