Abstract: A biological measuring device includes a light source that emits first light illuminating an area on a living body, an imaging device that detects second light returned from the living body and acquires a first image including at least part of the living body, and a control circuit that controls the light source. If a specific part of the living body is not located in a predetermined coordinate range in the first image, the control circuit restricts emission of the first light from the light source. The predetermined coordinate range is set outside the area.

Abstract: A measuring device includes: a light source that emits, toward a target part of an object, at least one light pulse group each including light pulses emitted sequentially, a photodetector that detects at least a part of at least one reflected light pulse group and including reflected light pulses sequentially returning from the target part, and a control circuit that controls the light source and the photodetector. The control circuit causes the light source to emit the at least one light pulse group within a first period, causes the photodetector to extract, within the first period, a first component that is a component of light included in at least a part of a leading reflected light pulse of the reflected light pulses, and causes the photodetector to output a first electric signal corresponding to the first component.

Abstract: An optical sensing apparatus includes a laser device, a photodetector, and a control circuit. The laser device includes a light source that emits laser light, a diffusing member having a diffusing surface that crosses an optical path of the laser light, the diffusing member making the laser light lower in intensity in a first portion, making the laser light higher in intensity in a second portion, and enlarging a beam diameter of the laser light, and a screen, and irradiates a physical object with the laser light having passed through the screen or the laser light reflected by the screen. The control circuit causes the laser device to irradiate the physical object with at least one optical pulse of the laser light and causes the photodetector to perform a time-resolved measurement of at least one reflected optical pulse of the laser light returning from the physical object.

Abstract: A device is used for measurement of an internal portion of an object and includes a light source that emits pulsed light with which the object is irradiated, a light detector that detects light which returns from the object in response to irradiation with the pulsed light, and a processor. The processor assesses temporal stability of a light amount of the light which returns from the object and is detected by the light detector.
