Claim:
1. An optical radiation detection system, comprising: an optical medium structured to define an optical region adapted to transmit the optical radiation and being associated with at least one electrical parameter varying in accordance with the optical radiation concerning said optical region; a first electrode and a second electrode electrically coupled to the optical medium; wherein at least one of said first and second electrodes is capacitively coupled to the optical medium and is spaced from said optical region by a dielectric material, an electric current or voltage generator connected to said first electrode and structured to provide an electric signal to be applied to the optical medium; an electric measuring circuit connected to said second electrode and structured to provide an electric measuring signal representing a variation of said at least one electric parameter of said optical region, wherein the first electrode is capacitively coupled to said to the optical medium and is spaced from the optical region by a distance chosen so as to substantially reduce a disturbance in amplitude, phase, frequency and polarization of the optical radiation due to said first electrode, wherein said distance is chosen so that an amplitude value of the electric field E(d) associated with the optical radiation which acts on said first electrode is lower than a maximum amplitude value of the electric field E
