摘要:

The paper researches on the offset error of self-triggering pulsed mini laser radar. It theoretically analyzes the variation of space charge region of PN junction in receiving photodiode. The variation value is affected by the different incident light power. One of conclusion is the laser pulse time-of-flight affected by the variation of incident light power. Another conclusion is the laser pulse width affected by the variation of incident light power as well. The paper proposes the basic equations to describe this phenomenon. In addition, the new designed experimental devices are used to prove that the theoretical analysis is true. This new system can effectively solve the offset error problems, and the negatively impact of offset error will be eliminated on the receiver of self-triggering pulsed mini laser radar system. © (2014) Trans Tech Publications, Switzerland.
