Paper Abstract

Energy spectrum estimation (i.e. evaluation) of optical radiation with the new spectrum analyzer is considered. This device is parallel resonant optical spectrum analyzer; its resolving system is a set of narrow–band optical resonators in the form of interference filters, each of which is equivalent to a system with lumped parameters. This allows us to consider only oscillations of the optical field in the form of scalar functions and adopt as a model of analyzed signal harmonized scalar random process. Photo detector operation and average of photocurrent using an integrator and integrating circuit is considered too. On the basis of the application prolate entire spheroidal wave function theory energy spectrum estimation by the integral of photocurrent is obtained. This estimation of the energy spectrum is consistent and asymptotically unbiased.
