Abstract
An optical thin film processor for the elaboration of unidimensional signals embodies a dielectric thin film transparent to laser radiation, shaped as a spherical lune having an angle of 270.degree., supported by a spherical substrate, formed of material having a refractive index lower than that of the thin film, a point source located on either meridian delimiting the thin film, detecting means on the other meridian, a modulator located on a meridian at 90.degree. relative to the input meridian, and a device lying on the meridian at 180.degree. from the input meridian for the space-filtering of a signal coming from the modulator on the 90.degree. meridian.
