Optical tomographic imaging equipment having a light source unit for generating a light wave having a predetermined coherence length

摘要

An optical tomographic imaging equipment including a light-receiving unit having a plurality of light-receiving elements, and an electronic focusing control unit. The electronic focusing control unit provides a control such that a plurality of light-receiving signals, derived by light-receiving an interference wave involved in superposition of the reflected light and the reference light using the plurality of light-receiving elements of the light-receiving unit, are relatively delayed and added to each other so as to issue resultant light-receiving signals involved in emphasis of information of a predetermined point on a light path of the object light within the subject.
