Abstract

In this paper, we consider possibilities to compensate the chromatic aberration effects in the swept source optical coherence tomography system with line-field illumination (LF SSOCT) in spectral range 1260-1360 nm and reflected light acquisition by linear array InGaAs photo detector. Compensation of chromatic aberrations is provided by combined use of optimized optical system design with sharp focusing independent on light wavelength and fringe processing algorithm which allows accurate spectral fringe frequency evaluation even in the case of nonlinearity of the wavenumber tuning. Experimental results confirmed significant enhancement of imaging quality including LF SSOCT mode.
