Abstract: The image display apparatus includes a light attenuation section that reflects a portion of light emitted from a light source and a scanning section that scans the light reflected by the light attenuation section. The light attenuation section transmits a portion of light emitted from the light source. The light attenuation section has reflectance and transmittance and the reflectance is smaller than the transmittance. The image display apparatus further includes a light receiving element on which the light transmitted through the light attenuation section is incident. The image display apparatus also includes a control section that controls activation of the light source in accordance with detection results of the light receiving element.

Abstract: A three-dimensional measuring device includes a human detection information receiver for receiving information from a human detection sensor that detects a person present within a detection range, a laser emitter for irradiating a region including the object with the laser beam, a laser emission controller for controlling power of the laser beam irradiated from the laser emitter to first power and second power lower than the first power, an image capturing device for imaging the object, on which the laser beam is irradiated, and acquiring image data, and a point-group-data generator for generating, based on the image data, three-dimensional point group data of a region including the object. When the human detection information receiver receives, from the human detection sensor, first information indicating that a person is absent from the detection range, the laser emission controller controls the power of the laser beam to the first power.

Abstract: An optical attenuator, when damaged, loses not only a light attenuation function but also part of an optical path shift function utilizing a refractive effect, and thus an optical path shift function in a normal state is lost. Thus, it is possible to diverts an optical path of modulate light, which is a laser beam, from a direction toward a mirror surface, that is, a direction toward the eye of an observer.
