Paper Abstract

We describe preliminary results of high-speed 2-dimensional Doppler OCT measurement using a unique optical frequency domain imaging (OFDI) system. SSG-DBR laser is the light source from which wave number is swept discretely over predetermined absolute values in equal wave number interval with constant output intensity. Multi-sampling at each wave number enables us to reconstruct multiple images by 1 transversal scan, and the 2 dimensional flow image is reconstructed from the phase Doppler shift between 2 successive images. Maximum detectable velocity is restricted by sampling rate, which is higher than A-scan flow has been carried out with this system adopting Kasai velocity estimator. The results predict that the method is valid for stationary flow.
