Experimental setup of GISC lidar.
Experimental reconstruction results for high-reflection targets we proposed at 900 m range (with M = 3000 measurements). (a) and (b) The original target plates imaged by a camera and a telescope, respectively; (c) the concrete sizes of a standard Chinese vehicle license plate; (f) the concrete sizes of a set of resolution panels; (d) and (g) are the targets' images reconstructed by GISC lidar and the targets are all represented in the space basis; (e) the imaging result obtained by replacing the PMT with a camera in Fig. 1 and accumulating 3000 measurements (the receiving aperture of telescope is 420 mm); (h) the cross-section of the rectangular selection box in (g).
Reconstruction results of a natural target (the overhead target of a tower) at 720 m range (with M = 3000 measurements). (a) and (b) are the image of the target imaged by a camera and a telescope, respectively; (c) is the target's image reconstructed by GISC lidar and the target is represented in two-dimensional discrete cosine transform (2D-DCT) basis.
