Abstract:
Based on an analysis of a system of cumulants of random values, analytical expressions are derived for characteristic functions and distribution densities, which describe signals in a channel of a Hartmann sensor. Likelihood ratio equation has been solved and an expression is obtained for statistically optimum estimate of local tilts measured with a sensor of Hartmann type.
