  • Patent number: 9823359
    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.

  • Patent number: 9476773
    Abstract: In a composite sensor, an arrangement region of thermal image sensors and an arrangement region of range image sensors are arranged so as to overlap each other as seen in the mounting direction. This makes it possible to acquire thermal and range images coaxially, thereby suppressing image misalignment between the thermal and range images. In the composite sensor, a seal body formed by mounting the first and second substrates on top of each other seals a space about the thermal image sensors in a vacuum state. This can prevent the heat occurring about the range image sensors from affecting the thermal image sensor side. In addition, the substrate arranged with the thermal image sensors and the substrate arranged with the range image sensors are separate from each other, which can secure a degree of freedom in designing.
