An optical control device is provided in a scanning optical device that applies light emitted from a light source to an observation target as spot light, and detects return light from the observation target while scanning the spot light, and includes an irradiation section that applies white light and special light to the observation target, an irradiation time control section that performs a control process so that an irradiation time of the special light is longer than an irradiation time of the white light, and a light detection section that detects first return light from the observation target when the white light for which the irradiation time is controlled has been applied to the observation target, and detects second return light from the observation target when the special light for which the irradiation time is controlled has been applied to the observation target. |
