title: Two-step incoherent optical method for the realization of a rho filter.
abstract: A simple incoherent optical method dor the realization of a rho filter is described. By means of the optical-transferfunction synthesis method, the required rho filter is obtained from two statistical low-pass filters. The processing system is illustrated, and some experimental results are also shown.
