Characteristics of the Measurement Unit of a Full-waveform Laser System

The analysis of data derived by full-waveform laser scanning systems is of great interest. In this study, we estimate the impulse response of a laser scanning system capturing the waveform. Considering the impulse response of the system is important for precise waveform analysis. The characteristic of the system has to be mentioned to interpret the pulse properties in an accurate way. We determined by experiments the impulse responses of the laser scanning system for different bandwidths, namely 250 MHz, 750 MHz, 1 GHz, and 6 GHz. By considering the impulse response the measured transmitted waveform of the emitted laser pulse can be adapted. The similarity of the adapted transmitted and received waveform is compared and discussed.
