Abstract: To prevent fluctuation in the correlation between the output of a light source and monitor light in a case where the output of the light source is changed.
A medical system according to the present disclosure includes an imaging device that images an observation target, and a light source device that generates light for irradiating the observation target. The light source device has: a multiplexer that multiplexes lights of different colors; a scattering unit that scatters the light multiplexed by the multiplexer; and a light receiving element that detects the light scattered by the scattering unit. By detecting the light scattered by the scattering unit, it is possible to prevent fluctuation in the correlation between the output of the light source and monitor light in a case where the output of the light source is changed.
