| 1 | Shot-noise limited, supercontinuum-based optical coherence tomography显示文摘We present the first demonstration of shot-noise limited supercontinuum-based spectral domain optical coherence tomography(SD-OCT)with an axial resolution of 5.9μm at a center wavelength of 1370 nm.Current supercontinuumbased SD-OCT systems cannot be operated in the shot-noise limited detection regime because of severe pulse-topulse relative intensity noise of the supercontinuum source.To overcome this disadvantage,we have developed a low-noise supercontinuum source based on an all-normal dispersion(ANDi)fiber,pumped by a femtosecond laser.The noise performance of our 90 MHz ANDi fiber-based supercontinuum source is compared to that of two commercial sources operating at 80 and 320 MHz repetition rate.We show that the low-noise of the ANDi fiber-based supercontinuum source improves the OCT images significantly in terms of both higher contrast,better sensitivity,and improved penetration.From SD-OCT imaging of skin,retina,and multilayer stacks we conclude that supercontinuumbased SD-OCT can enter the domain of shot-noise limited detection. | Shreesha Rao D.S.
