PROBLEM TO BE SOLVED: To obtain a light control unit capable of forming a wide band of light by combining a plurality of luminous fluxes with high efficiency, and an optical tomographic imaging device capable of acquiring a tomographic image of high resolving power at a high speed using the light control unit. SOLUTION: The optical tomographic imaging device 1 is equipped with the light control unit 10 for combining a plurality of luminous fluxes to output the same. The light control unit 10 is equipped with an emission part 11 capable of emitting at least three luminous fluxes respectively swept in wavelength within mutually different wavelength bands, wavelength combination means 15a and 15b having a wavelength selectivity for combining at least two luminous fluxes among at least three luminous fluxes to emit them and a control means 16 for controlling so as to output at least one luminous flux to a time zone different from at least another one luminous flux on the upstream or downstream side of the emission part 11 and the wavelength combination means 15a and 15b in a luminous flux light path. At least two luminous fluxes mutually different in wavelength are combined to be outputted at the same time. COPYRIGHT: (C)2008,JPO&INPIT |
