Paper Abstract

Electronic component improvements allow everyone to use them for performing new features in different applications. Lidar signal control is matter of continuous design and it can be studied in order to increase signal-to-noise ratio. Fortunately, the advent, of programmable gain amplifiers, switching capacitor filters and specific AD converters, is the stimulus of improving lidar signal quality. The main scope of this paper is to design and to realize a hardware simulator capable of reproducing the behavior of lidar signal control. This paper aims at describing the results of an automatic control system for Raman lidar signals. The system is based on the following units: laser source, damper, PMT (Photomultiplier), current - to - voltage converter, switched capacitor filter, programmable gain amplifier, A/D converter and FIR filter. This configuration allows the use of FIR filter that is not strictly necessary but it can help in adapting signal according to the amplitude. One of the main advantage of this system is to obtain a flexible and programmable board.
