Figure 1From: Full Waveform Analysis for Long-Range 3D Imaging Laser Radar(a) Schematic diagram indicating the principal components of the scanning system. Electrical paths are denoted by solid lines, optical paths by dashed lines. Si-SPAD is a silicon single-photon avalanche diode. (b) The transceiver head assembly. The system dimensions are approximately 275 mm by 275 mm by 175 mm. The two galvanometer servo-control circuit boards (not visible) are on the underside of the slotted baseplate.Back to article page
