ABSTRACT:
A light control unit that combines and outputs a plurality of light beams, including: a light emission section capable of outputting three or more light beams swept in wavelength within different wavelength ranges from each other; a wavelength combining section having wavelength selectivity, that combines and outputs at least two of the three or more light beams; and a control section that performs control in the light emission section, or upstream or downstream of the wavelength combining section in the optical path of the light beams to cause at least one light beam is outputted during a time period which is different from a time period in which another one or more light beams are outputted, thereby two or more light beams having different wavelengths from each other are combined and outputted at the same time.
