Abstract

Fourier domain optical coherence tomography requires either a linear-in-wavenumber spectrometer or a computationally heavy software algorithm to recalibrate the acquired optical signal from wavelength to wavenumber. The first method is very sensitive to the position of the prism incorporated in the spectrometer, while the second method drastically slows down the system speed when it is implemented on a serially oriented central processing unit. In this manuscript, a Fourier domain ultra-fast optical coherence tomography system operating in the 1 μm range with real-time data resampling is presented for the first time. It utilizes a newly released 1024 pixels line scan InGaAs camera able to acquire data as fast as 91,900 lines per second. To demonstrate the performance of the system, images from a thumb of a volunteer obtained with real-time processing and displaying are shown.
