Spectral linewidth of incidence light can be found by statistical distribution of photoelectric pulses.However, a detector has dark pulses and dark pulses distort the statistical properties of the distribution.When dark pulses have Poissonian distribution, the linewidth of incident light can be known by taking into account dark pulse contribution.In this work, statistical properties of photoelectric pulses have been investigated after the investigation on the dark pulses.It has been found that the distributions of dark pulses, the laser light, and the thermal light are exactly Poissonian.According to the fact that dark pulses had Poissonian distribution, the spectral linewidth of sacttered laser light has been determined by using the departure from Poissonian distribution.
