Abstract: An observation device is an observation device observing an observation target and includes: an emission light source that generates emission light; a projection light source that generates projection light; a scanning mirror that scans the emission light and the projection light toward the observation target along the same optical path; a light guide optical system that guides detection target light generated in the observation target in accordance with emission of the emission light without it passing through the scanning mirror; an optical detector that detects the detection target light guided by the light guide optical system; and a control unit that controls an intensity of the projection light on the basis of a result of the detection of the detection target light.
