Abstract: A distance measuring device that measures a distance to an object. The distance measuring device includes: a light source that emits pulsed light; a reflector that reflects and radiates, as radiation light, the pulsed light emitted from the light source, and reflects object light that is the radiation light reflected by the object and returning; and an imager that captures the object light reflected by the reflector. The pulsed light emitted from the light source is diffused light. The light source and the imager are located to face the reflector. The reflector radiates, as the radiation light, light in a shape with a long axis and a short axis. The imager performs exposure in synchronization with the pulsed light to image the object light.

Abstract: A visible light communication system includes a light transmitter including a group III nitride semiconductor laser element and a wavelength converter provided to face a light exit surface of the nitride semiconductor laser element and containing a fluorescent material. The visible light communication system further includes a wavelength filter configured to remove light emitted from the fluorescent material and a light receiving element configured to receive light emitted from the group III nitride semiconductor laser element via the wavelength filter.

Abstract: A drive element includes: a fixing part; a drive part placed on a lateral side of the fixing part and coupled to the fixing part; and a movable part configured to be driven by the drive part. A lower electrode, a piezoelectric layer, and an upper electrode are formed in order in an upper surface region of the fixing part and the drive part, and in a wiring region on the fixing part side of the upper surface region, a low dielectric layer containing at least one element forming the piezoelectric layer is formed on an upper surface of the piezoelectric layer.
