ABSTRACT:
An anti-parallax scintillator system images light from a face of a scintillator radiated by penetrating ionizing radiation from a localized source. Radiation from the source will traverse the scintillator along rays forming a cone having its vertex approximately at the source. Scintillator light directed along each such ray is collected and redirected toward an aperture in a screen between the scintillator and the photocathode of an image intensifier. The aperture transmits the redirected light which is then incident upon the photocathode to form an image. Scintillator light not directed along rays from the vertex will miss the aperture and be blocked from the photocathode by the screen. A second embodiment, without an aperture, uses a plurality of mirrors arranged in a quasi-Newtonian configuration to provide anti-parallax imaging.
