Abstract: Flat panel image sensor (10) is provided by combining photoconductive imaging electrodes of a vidicon with a two-dimensional array of cold cathode field emitters (14) commonly used for flat panel field emission display (FED) systems. The FED operates normally to emit electrons which are accelerated in prior art displays towards a luminescent phosphor to generate light output proportional to the cathode emission. Rather than accelerating towards a phosphor, electrons are accelerated towards a photoconductor layer (16) to replace charge removed from the layer by an incident radiation pattern directed at the photoconductor layer (16) through a layer of transparent, electrically-conducting material (17) which serves as a radiation window. The transparent, electrically-conducting layer (17) may be partitioned to reduce stray capacitance for large area sensors and the partitioned, electrically-conducting layer (17) permits a parallel readout mode of operation.

Abstract: Un système d'acquisition d'images emploie des diodes à effet latéral espacées afin d'acquérir des signaux traités pour produire des signaux indicatifs d'une image tridimensionnelle d'un objet. Un endoscope (50) est adapté pour fonctionner conjoitement avec un scanner optique (12) produisant un faisceau de rayonnement traçant une trame (62). L'endoscope (50) emploie au moins un canal optique comprenant un faisceau de fibres optiques (52) souples cohèrentes. On emploie des photodétecteurs élémentaires que l'on peut monter soit à l'extrémité distale de la sonde endoscopique (50) soit à l'extrémité proximale de cette dernière (50), afin de capter le rayonnement réfléchi et de produire un signal vidéo. On peut aussi employer le canal optique pour la transmission d'un faisceau de thérapie. L'endoscope (50) est capable d'obtenir des images multispectrales et multidimensionnelles du tissu en cours d'examen.
