The present invention relates to a dual focusing optical coherence imaging system. The dual focusing optical coherence imaging system includes: a light source unit for generating broadband light a main optical distributor for distributing the light generated from the light source to allow the light to be propagated an interference unit including first and second interference parts for forming interference signals with respect to different focused areas of an object to be detected using the light distributed from the optical distributor, and a common sample arm commonly connected to the first and second interference parts an optical switch connected to the first and second interference parts to select at least one of the interference signals transmitted from the first and second interference parts and a detection unit for converting the interference signal selected by the optical switch according to a preset mode into an electrical signal.
