Abstract
Using a continuous wavelet transform, the parameters of the noise generated in a balanced laser radiation detector at the output of an optical power divider were studied. A procedure for mathematical signal processing based on the optimization of the parameters of the wavelet transform is proposed, which made it possible to significantly increase the degree of randomness of the generated noise. The increase in the degree of randomness was demonstrated using the Longest Run test of the NIST package.
