ABSTRACT:
A light collector collects and detects light emitted from a photostimulable phosphor sheet in a photostimulable phosphor imaging system. The collector includes a vertical mirror extending the width of the phosphor sheet; and a V-roof mirror having upper and lower mirrors forming an apex facing the vertical mirror. The vertical mirror and V-roof mirror form slots for passing a scanning beam of stimulating radiation through the collector to the surface of the photostimulable phosphor sheet and for admitting emitted light from the phosphor sheet into the collector. The vertical mirror and V-roof mirror form a substantially triangular cross-section which diminishes in size from one edge of the phosphor sheet to the other edge thereof. A photodetector is positioned at the large end of the triangular collector for receiving light emitted from the photostimulable phosphor sheet and for generating an electrical signal in response thereto.
