Paper Abstract

In order to enhance the longitudinal resolution and the signal to noise ratio (SNR) of Spectral domain OCT (SDOCT), a SDOCT using white light source is developed. By analyzing relationship between axial total number of pixels in the horizontal direction of CCD, spectrum of white-light source and longitudinal resolution, a white-light source SDOCT(WSSDOCT) based on partial spectrum analysis is developed and introduced. Proper white light source required and band width for detection selected, SNR is improved with maximum detecting depth and high longitudinal resolution guaranteed. Experimental results validate the measurement method for the coherence length of the light source, and system and image longitudinal resolution, and also testify the feasibility of WSSDOCT.
