A laboratory demonstration of Fresnel telescope synthetic aperture imaging ladar system is presented. The target is two-dimensional (2D) scanned by a beam that is combined by two concentric and coaxial quadratic wavefont laser beams with orthogonal polarization. The scattered signal light from the target is collected by a telescope and is split into two beams by a polarized beamsplitter. The two separated beams then pass through a half and quarter waveplate, respectively, and enter a 90 degree 2×4 optical hybrid. The four outputs of optical signals from optical hybrid are detected by two pairs of balanced detectors and then stored in computer using AD converters. The image of the target can be reconstructed from the data acquired by 2D scanning through data processing. A point image of 0.3 mm×0.3 mm and 2D Chinese character are reconstructed in experiments with high resolution and contrast. The expected speckles are also observed in the reconstructed image that commonly existed in coherent imaging. The experimental results prove the correctness of the concept of the Fresnel telescope synthetic aperture imaging ladar.
