We have realized the swept source optical coherence tomography(SS-OCT) by using the self-fabricated wavelength swept laser(wavelength tuning range : 80㎚, line-width : 0.12㎚, wavelength sweeping rate : 50㎐). In addition, we have used the dual balanced detector that could make a mirror image in OCT display suppressed. We can also fabricate the comb filter of Michelson interferometer type for fast-signal processing in OCT. Using this SS-OCT system for measuring an mirror, a 1㎜-depth glass and an onion, we confirmed that the in vivo epidermal cross-sectional images for them can be obtained appropriately.
