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.
