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.
Abstract translation: 在复合传感器中，沿着安装方向看，热图像传感器的排列区域和范围图像传感器的布置区域被布置成彼此重叠。 这使得可以同轴地获取热和范围图像，从而抑制热和距离图像之间的图像未对准。 在复合传感器中，通过将第一和第二基板彼此顶部安装形成的密封体在真空状态下封闭围绕热像传感器的空间。 这可以防止范围图像传感器发生的热量影响热图像传感器侧。 此外，布置有热图像传感器的基板和布置有范围图像传感器的基板彼此分离，这可以确保设计的自由度。

Abstract: An actuator device includes a support part, a first movable part, and a second movable part. The second movable part includes a pair of first connection portions positioned on both sides of the first movable part on a first axis and connected to a pair of first connecting parts, and a pair of second connection portions positioned on both sides of the first movable part on a second axis and connected to a pair of second connecting parts. An outer edge of each of the pair of the first connection portions includes a first linear portion that extends along a second axis direction. An outer edge of each of the pair of the second connection portions includes a second linear portion that extends along a first axis direction.

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 as a central line and a second drive signal for swinging the mirror with respect to the second axial line as a central line. In a lighting-on period in which a light source emits laser light in one swing of the mirror with respect to the second axial line as a central line, the control unit generates the first drive signal and the second drive signal by repeating a process of generating N pieces (N is an integer of two or greater) of second signal elements which respectively constitute the second drive signal with respect to a first signal element in a ½ cycle period in the first drive signal.

Abstract: A projection display device includes: a light source that emits a first and a second laser lights; a scanning drive mirror that reflects the first and the second laser lights, and uses the first and the second laser lights in scanning; a light diffusion unit that includes a predetermined region that allows the first laser light to be transmitted therethrough, and diffuses the first laser light; a light detection unit that detects the second laser light that passed the predetermined region; and a control unit that executes a process to detect the second laser light, and determines a state of the predetermined region on the basis of a detection value of the light detection unit. In a case where the control unit determines that a defect occurs in the predetermined region as the state, the control unit executes a process to stop displaying the projection.

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.
