The control circuit causes the light source to emit the at least one first light pulse and the at least one second light pulse at different timings. The control circuit causes the photodetector to detect a first component and output a first electric signal representing the first component. The control circuit causes the photodetector to detect a second component and output a second electric signal representing the second component.

Abstract: A distance-measuring device includes a light source, a light detector, and a circuit. The circuit causes the light source to output a light pulse toward a target object, causes the light detector to detect a reflection-light pulse in a first period and a second period to generate a first signal and a second signal, respectively, and generates and outputs data indicating a distance from the light detector to the target object based on the two signals. The first period includes at least a part of a rise period, from a first point at which an intensity of the reflection-light pulse starts increasing to a second point at which the increase ends, and the first point. The second period includes at least a part of a fall period, from a third point at which the intensity starts decreasing to a fourth point at which the decrease ends, and the fourth point.

Abstract: An optical measuring device includes a light source, a photodetector, a control circuit, and a signal processing circuit. The control circuit causes the light source to emit first and second light pulses with which a target of measurement is irradiated, causes the photodetector to detect a first portion of a first reflected light pulse in a first period having a first time length and output a first signal representing an amount of light of the first portion, and causes the photodetector to detect a second portion of a second reflected light pulse in a second period having a second time length and output a second signal representing an amount of light of the second portion. The signal processing circuit generates, based on a fluctuation in the first signal and a fluctuation in the second signal, information indicating a fluctuation in internal state of the target of measurement.
