Abstract

A position-sensitive detector for electronically imaging objects emitting low-intensity light radiation, comprises a photocathode means for converting incident low-intensity light radiation into electrons; electron acceleration means disposed in series with the photocathode means for accelerating the electrons generated by the photocathode means; transducer means disposed in series with the acceleration means for converting the accelerated electrons into ultra-violet radiation; and a multi-wire chamber means disposed in series with the transducer means for providing readout of the position of the ultra-violet radiation. A detector having a solid scintillator for electronically imaging objects emitting low-intensity x-ray or gamma ray or the like is also disclosed.
