Abstract: A biological information measuring device according to an aspect of the present disclosure includes: a light source that, in operation, emits irradiation light for irradiating a test portion of a subject; a light detector that, in operation, detects light from the subject and outputs an electrical signal corresponding to the light; and a control circuit that, in operation, determines a power of the irradiation light emitted by the light source, and that, in operation, measures biological information related to a blood flow at the test portion based on the electrical signal. The control circuit, in operation, detects a distance between the light source and the test portion based on the electrical signal, and determines the power of the irradiation light such that the power of the irradiation light is increased as the distance increases.

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: 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: An imaging apparatus includes: a light source that emits a light pulse onto an object, and a light detector that detects a reflected light pulse returning from the object. The light detector detects a first part of the reflected light pulse in a first period, and detects a second part of the reflected light pulse in a second period that starts after the first period. The first period includes at least a part of a rising period, the rising period being a period from start to end of increase of intensity of the reflected light pulse. The second period includes a part of a falling period, starts after start of the falling period and does not include the start of the falling period, the falling period being a period from start to end of decrease of the intensity.
