Abstract

In this paper, a fiber OCT system illumined by a superluminescent diode in the 940 nm wavelength region is reported. To test the 940nm OCT system, ex-vivo rabbit bladder, porcine bladder and rat bladder with tumor were imaged and compared with 1320nm OCT. The results demonstrate that the 940nm OCT system provides higher axial resolution up to 5 μm and less speckle noise, but the experimental results showed that the image depth for bladder samples in the 940 nm OCT system is slightly lower than the 1300nm OCT due to water absorption. During experiments, it was found that the fiber caused more dispersion at the wavelength of 940 nm than 1320 nm.
