<p>PURPOSE:To obtain a planar position displaying laser radar which is the most appropriate for a vehicle mounted short distance radar and the like. CONSTITUTION:The laser radar in this invention is provided with a laser luminous part 1 radiating pulse shaped laser beam, an optical scanning part 3 making the laser beam scan in a plane, a light receiving part 2 receiving reflected beam via the optical scanning part and converting it to analog electric signal, an A/D converter part 4 converting the analog signal to digital signal, a signal processing part 5 detecting distance upto a target which generates reflected beam in the relation ship between time and level of the digital signal, and producing a planer position displaying signal analog with synchronizing with scanning information of the optical scanning part, and a display part 6 displaying the protruded planer position display signal.</p> |
