ABSTRACT:
A light detecting device for reliably detecting weak luminescing at a random position in a predetermined spatial area. The light detecting device has a fluorescent fiber containing a fluorescent coloring matter and a flat or curved concentrator having a primary surface, on which the fluorescent fiber is fixedly arranged with the axis thereof in parallel relationship to the primary surface. A light receiving means is connected to at least one end of the fluorescent fiber.
