Ultraviolet downconverting phosphor for use with silicon CCD imagers.
The properties and application of a UV downconverting phosphor (coronene) to silicon charge coupled devices are discussed. Measurements of the absorption spectrum have been extended to below 1000 A, and preliminary results indicate the existence of useful response to at least 584 A. The average conversion efficiency of coronene was measured to be ~20% at 2537 A. Imagery at 3650 A using a backsi...
متن کاملمقایسه سنسورهای دیجیتالی Charge-Coupled Device با Photostimulable Phosphor Storage Plate در تشخیص شکستگی عمودی ریشه در دندانهای اندو شده (مطالعه آزمایشگاهی)
Objective: Vertical root fracture (VRF) is among the most common causes of endodontic treatment failures. This study aims to compare charge-coupled devices (CCD) and photostimulable phosphor plates (PSP) for detection of vertical root fractures in endodontically treated teeth. Methods: In this diagnostic in vitro study, 40 maxillary anterior teeth were selected and after preparation and roo...

متن کاملA comparative study of image quality and radiation exposure for dental radiographs produced using a charge-coupled device and a phosphor plate system.
AIM To investigate the quality of periapical radiographic images produced by two digital dental radiography systems, a charge-coupled device (CCD) and a photostimulable phosphor (PSP) image plate system, and to examine the overall radiation exposure when using these systems in a clinical setting. METHODOLOGY Patients were randomly allocated to both systems and the resultant radiographs rated ...
متن کاملA Fast-readout CCD System for Configured-Detector Imaging in STXM
This paper describes a configured-detector imaging system based around an electron-multiplying CCD (iXon DV860 from Andor Technology) that combines fast frame-transfer readout with very high sensitivity. The detector consists of a Peltier-cooled CCD array of 128 by 128 sensors, and makes use of visible light coupling to a phosphor screen, to make it easy to operate over a wide range of photon e...
