采用线性调波长的1.55 μm光纤激光和一个控制照明光束方向的旋转平面镜，建立了聚束模式合成孔径激光雷达(SAL)成像演示实验室装置。该装置运转稳定，能够产生与其成像理论预期完全相符的高分辨率成像。给出了典型的聚束模式SAL高分辨率成像结果，包括合作目标成像、非合作目标成像、对同一目标的持续跟踪成像以及相干叠加成像与非相干叠加成像。

By using a linearly wavelength-scanning 1.55 μm laser source and a rotating plane mirror to control the direction of the illuminating laser beam, a laboratory-scale spotlight mode synthetic aperture ladar (SAL) is established. The SAL operates stably and the generating high resolution images are in accordance with the prospective results of imaging theory. Typical spotlight mode SAL images are illustrated, including images of a cooperative target, images of a diffusive target, constant tracking images, coherent superposition images and incoherent superposition images of the same target.
