Abstract
A measurement device includes a first light emitting unit that emits light with a first wavelength onto a measurement site, a second light emitting unit that emits light with a second wavelength different from the first wavelength onto the measurement site, a light receiving unit that receives light which passes through an inside of the measurement site and generates a detection signal, and an analysis processing unit that calculates a degree of oxygen saturation from the detection signal. Distances between light emission positions by each of the first light emitting unit and the second light emitting unit and a light reception position by the light receiving unit are variable.
