SEMICONDUCTOR RADIANT RAY DETECTOR

摘要

PURPOSE:To obtain a detector of high resolution with a high detection efficiency by distributively coupling the semiconductor photo detecting element and a fluorescent material in parallel through a light wave guiding layer provided on the mounting base. CONSTITUTION:A light wave guiding layer 35 is provided on the mounting base 31 serving as collimator. A semiconductor photo detecting element 32 (33 is the receiving section of the element 32) sensitive to the radiant rays and a fluorescent material 34 are arranged in parallel on the layer in such a manner as to be distributively coupled thereto to form a detector. The light wave guiding layer 35 is made of a substance, such as polystylene, glass and quartz.
