Abstract

According to the application of underwater lidar imaging, a high speed optoelectronic imaging module was developed. On the basis of traditional technology of ICCD, the high speed blue-green enhanced multi-alkali cathode was developed, A number of key technologies have been breached for range gating, including low delay and high speed gating, high precision delay control, high speed automatic gain control. A high-precision gated ICCD module with minimum gate width of 3ns, jitter less than 100ps and 100ps minimum delay step was developed. The test conditions of range gated imaging in air were established, the depth of field was less than 2m，the imaging blind area limit is less than 2.5m. The effective detection distance underwater was 50m.
