An electronic method of k-space linearization for an analog 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 nonlinear 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, the FWHM of the point spread function is reduced by a factor of 5.6 and sensitivity is increased by 9.8 dB.
