    Abstract: Each light detecting unit includes a semiconductor region that outputs a carrier, and a surface electrode. In a photodiode array, a read wire is positioned between neighboring avalanche photodiodes. When a plane including a surface of the semiconductor region is set as a reference plane, a distance tb from the reference plane to the read wire is larger than a distance to from the reference plane to the surface electrode.

    Abstract: A photodetector device includes an avalanche photodiode array substrate formed from compound semiconductor. A plurality of avalanche photodiodes arranged to operate in a Geiger mode are two-dimensionally arranged on the avalanche photodiode array substrate. A circuit substrate includes a plurality of output units which are connected to each other in parallel to form at least one channel. Each of the output units includes a passive quenching element and a capacitative element. The passive quenching element is connected in series to at least one of the plurality of avalanche photodiodes. The capacitative element is connected in series to at least one of the avalanche photodiodes and is connected in parallel to the passive quenching element.

    Abstract: A photodetecting device includes a semiconductor substrate including a one-dimensionally distributed plurality of pixels. The photodetecting device includes, for each pixel, a plurality of avalanche photodiodes arranged to operate in Geiger mode, a plurality of quenching resistors electrically connected in series with the respective avalanche photodiodes, and a signal processing unit arranged to process output signals from the plurality of avalanche photodiodes. Light receiving regions of the plurality of avalanche photodiodes are two-dimensionally distributed for each pixel. Each signal processing unit includes a gate grounded circuit and a current mirror circuit electrically connected to the gate grounded circuit. The gate grounded circuit is electrically connected to the plurality of avalanche photodiodes of the corresponding pixel via the plurality of quenching resistors. The current minor circuit is arranged to output a signal corresponding to output signals from the plurality of avalanche photodiodes.

    Abstract: A radiation image detecting device includes a photodetecting element that detects fluorescence light, and a prism that is disposed on an optical path of excitation light traveling toward an imaging plate and between the photodetecting element and the imaging plate. The prism includes, as surface thereof, a side face that is opposed to the imaging plate, and a side face and a side face that are inclined relative to the side face. The prism is disposed so that the excitation light incident through the side face propagates inside and is output from the side face and so that reflection from the imaging plate incident through the side face propagates inside and is output from the side face. The photodetecting element is disposed so as to be opposed to a region different from a region where the reflection from the imaging plate is output, in the surface of the prism.
