Zusammenfassung:	An optical signal processor having a monolithic prism supporting one or more channels, and constructed from a first glass block joined to a second glass block at a beam splitter interface. The monolithic prism has thin film beam splitters and filters (such as I and Q filters) either deposited directly on the prism or attached to it. The beam splitter interface, and the thin film beam splitters and filters are arranged relative to each other so that a portion of the return-ranging collimated encoded beam from an external optical sensor is reflected to all the filters. And detectors are connected over the filters to detect particular components of the collimated encoded beam which are passed through the respective filters. L'invention concerne un processeur de signal optique présentant un prisme monolithique servant de support à au moins un canal, et construit à partir d'un premier bloc de verre assemblé à un second bloc de verre, au niveau d'une interface de division de faisceau. Ce prisme monolithique présente des filtres et des diviseurs de faisceau à films minces (notamment des filtres I et Q) qui sont soit directement déposés sur le prisme, ou fixés sur celui-ci. L'interface de division de faisceau, ainsi que les filtres et les diviseurs de faisceau à films minces sont agencés les uns par rapport aux autres de sorte qu'une partie du faisceau codé collimaté compris dans la plage du retour, provenant d'un capteur optique extérieur, est réfléchie sur tous les filtres. Des détecteurs sont accouplés au filtre pour détecter des composants particuliers du faisceau codé collimaté, qui traversent les filtres correspondants.
