The advantage and disadvantage of different scannerless three-dimensional laser imaging systems was compared, the intensity modulation scannerless three-dimensional laser imaging technology based on multi-channel receiver was proposed. The technology has the advantage of fast imaging, high precision, high reliability, long distance. The high power pulse laser as the illumination source, two ICCD received the echo from dual channel sub optical system at the same time, the distance information was analyzed through the ICCD intensity information. The technology principle and approach was introduced. The principle sample machine was designed, and on which the imaging experiment was carried out. The experiment result shows that the imaging range is 5.1 km, range resolution is 0.25 m when range is 30 m.
