Wavelength-Tunable Light Source Apparatus, Driving Method Thereof, Optical Tomographic Image Acquisition Apparatus Including Wavelength-Tunable Light Source Apparatus, and Optical Tomographic Image Acquisition Method

摘要

A wavelength-tunable light source apparatus that has a wavelength-tunable light source that simultaneously operates a plurality of light sources with different wavelengths to emit light, includes:
a plurality of variable-wavelength light generation units forming the wavelength-tunable light source;a multiplexing unit configured to multiplex light of a plurality of wavelengths generated by the variable-wavelength light generation unit so as to be adjusted to one waveguide; anda control unit configured to control the plurality of the variable-wavelength light generation units to emit the light with different wavelength simultaneously in at least part of time, and control optical intensity such that wavelength dependence of the optical intensity generated from the plurality of variable-wavelength light generation units becomes unimodal.
