In this paper, a random noise study is carried out, generated by an optical random number generator based on an InGaAs p-i-n photodiode. The influence of the procedure of equalization of the energy values of the of the continuous wavelet transform on the efficiency of passing the test for the FFT randomness from the set of NIST statistical tests.
The study of noise generated by a system homodyne detection of laser radiation was made when random noise is recorded at the outputs of anoptical beam splitter after differential detection of signals. We studied the dependence of noise parameters on the length of the signal sequence sample and the effect of detrending using wavelet analysis. The NIST test suite was used to evaluate the degree of randomness of the generated noise sequence.
