Imaging by single-slit streak tube laser lidar

A new type of three-dimensional (3D) imaging laser radar is introduced. It uses streak tube as the receiver, which makes the radar have the peculiarities of high frame rate and wide range angle. The principle of this method is introduced theoretically. The imaging ability of this method to far distant object was demonstrated experimentally. A laser imaging demonstration system was established. Some key parameters were measured, and some specially objective streak image of indoor and outdoor were accessed. The method was proved to be available.
