Lidar is a high precision instrument. Now we design a new control platform which based on virtual instrument technology. By using virtual instrument technology,we assemble all the control and measurement instruments of lidar into one software platform which make control more flexible and reliable. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. LabWindows/CVI is a software development environment for C programmers. Access powerful function libraries for creating data acquisition and instrument control applications. The platform can real-time measure and analyze signal. Contains instrument control and data acquisition.
