Ghost imaging lidar via sparsity constraints

For remote sensing, high-resolution imaging techniques are helpful to catch more characteristic information of the target. We extend pseudo-thermal light ghost imaging to the area of remote imaging and propose a ghost imaging lidar system. For the first time, we demonstrate experimentally that the real-space image of a target at about 1.0 km range with 20 mm resolution is achieved by ghost imaging via sparsity constraints (GISC) technique. The characters of GISC technique compared to the existing lidar systems are also discussed.Comment: 4pages, 3figure

Predictions of input pinion floating on concentric face gear transmission static load sharing

A static load sharing analysis model of concentric face gear transmission associated with the input pinion floating is constructed, and the calculation method of static load sharing is proposed. The influence of the input pinion floating on static load sharing is predicted. The results show the input pinion floating stiffness reduction could benefit for the concentric face gear transmission static load sharing
