Purpose of this work is to introduce results of biological objects measurements with Optical Coherence Tomography system working with swept source laser (OFDI system). This specified source with spectrum centred around 1040 nm is dedicated to measure posterior segment of the eye. OCT with this wavelength is expected to be next generation for this sort of systems. Although commonly used 800 nm source enables imaging retina, deeper tissue layers are not available with this wavelength. Longer wavelengths in range of infrared spectrum (e.g. 1040 nm) are being weakly scattered which enables to go down to the choroid layer [1]. Examination this structure composed mostly from blood vessels might be very important for early diagnosis of eye diseases. In this paper system setup, swept source scheme and eye images would be introduced.
