Abstract (en)
[origin: EP0603036A1] Optical processing device for electrical signals including: - an optical source (L) emitting a multiwavelength beam (B1); - a modulator (MOD) modulating this beam; - an optical fibre (F) receiving the modulated beam (B2) and variously delaying the components corresponding to the various wavelengths; - a dispersive grating (H) dispersing in different directions wavelengths contained in the modulated beam (B3); - a spatial light-modulator (SLM) controlling the optical intensity level of various directions of the dispersed beam (B4); - an optical detection system (PD) receiving the beam (B5) processed by the spatial light-modulator (SLM). Application: transverse filter - UHF signal correlator. <IMAGE>
