Paper Abstract

The traditional pulse laser ranging system based on the measurement of time of flight often ignores the nonlinear influence of the intensity of the echo light power on the range error of the receiver system. Based on the transistor model (Gummel-Poon model), this paper makes a systematic modeling of the pulsed laser range finding receiver system. By means of computer aided analysis, the relationship between the input current waveform and the leading edge of the response pulse of the receiving system is analyzed. And thus, the relationship model of the echo light power and front of response echo pulse is derived in the paper. Based on the above model and by involving the method of differential threshold time discrimination, the walking error in the laser ranging system is corrected. Finally, the experimental results show that this method can effectively correct the nonlinear error caused by the fluctuation of the echo power and improve the accuracy of the ranging system.
