PURPOSE: A high resolution OCT(Optical Coherence Tomography) system is provided to improve the resolution and the measurement depth of a sample tissue by using a high molecular WINC(Wavelength Independent Coupler) which distributes a wavelength band. CONSTITUTION: A light source(1) outputs a signal of a wide band. A high molecular broadband coupler distributes a desirable wavelength band. The high molecular broadband coupler is comprised of a first coupler(3), a circulator(3'), and a second coupler(3''). The first coupler transmits an optical signal of a broadband to a tissue test sample(4) and a reference mirror(5). The circulator outputs the optical signal which is scattered and reflected from the sample and the reference mirror. A second coupler receives an optical signal. The second coupler transmits the optical signal to the detector.
