Abstract: A scanning device includes an MEMS mirror mechanism that swings a mirror with respect to a first axial line as a central line and swings the mirror with respect to a second axial line as a central line, and a control unit that generates a first drive signal for swinging the mirror with respect to the first axial line, and a second drive signal for swinging the mirror with respect to the second axial line. The control unit generates the first drive signal and the second drive signal so that m times of reciprocation of an irradiation region in a first direction and one time of reciprocation of the irradiation region in a second direction correspond to each other by repeating generation of a second signal element constituting the second drive signal to correspond to a first signal element in a period equal to or less than one cycle in the first drive signal.

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.
