摘要
A static-mode synthetic aperture imaging ladar （SAIL） in which the target and carrying platform are kept still during the collection process is proposed and demonstrated. A target point of 0.5 mm× 0.5 mm and a two-di- mensional （2D） object are reconstructed in the experiments, in which an optical collimator with a focal length of 10 m is used to simulate the far-field condition. The achieved imaging resolution is in agreement with the theo- retical design. The static-mode down-looking SAIL has the capability to eliminate the influence from the atmos- pheric turbulence and can be conveniently operated outdoors.
