Abstract

An electronic method of k-space linearization for an analogue camera for use in optical coherence tomography is demonstrated. The method applies a chirp to the data transfer clock signal of the camera in order to temporally compensate for diffraction that is non-linear in wavenumber. The optimum parameters are obtained experimentally and theoretically and are shown to be in good accordance. Close to maximum measurable axial range, by applying this method, we report a narrowing of the FWHM of the point spread function by a factor of 5.6 and improve its magnitude by 9.8 dB.
