Multicanal data acquisition system for lidar measurements

摘要

The use of lidar systems as distance noncontact devices by the control of the parameters of phenomena for ecological protection needs a development of technical capabilities for the realization of that idea. The high dynamics of the processes in the phenomena can be measured only with the real-time data acquisition system. The real-time working system allows an express analysis of lidar information. The lidar signal includes information of the parameters of the ecological pollution. In such systems as a control device are personal microcomputers, with special software. The stream of the information into the lidar systems usually needs two or more input canals and have an input speed about 20 Mbytes/canal. It is difficult for the microcomputers to collect this data directly, without additional devices.
