An optical tomographic imaging information acquisition apparatus according to an SD-OCT system including: at least two super luminescent diodes; a sensor and a spectrometer that are for acquiring information on a measurement target; a combiner section for the photoreceptor unit configured to combine emitted beams from the at least two super luminescent diodes (SLDs) and to guide the beams to the photoreceptor unit; a monitor unit configured to monitor a spectrum of the emitted beams from the at least two super luminescent diodes; a driving unit configured to drive the SLDs; and a control unit configured to feed back a monitored result by the monitor unit to the driving unit, the driving unit is further configured to drive only one of each of the at least two super luminescent diodes. With the apparatus, a spectral shape can be easily controlled to be unimodal.
