  • Patent number: 10352853
    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.
