Abstract: The present invention relates to the field of instruments for imaging internal structures of the human body, and in particular of the eye. More specifically it relates to an optimized process and an optical coherence tomography system thereof to measure the distances between the eye interfaces that is, the corneal surfaces, the surfaces of the crystalline lens, the retina and so on. A tiltable selection means, e.g. a titable mirror, is used to switch between different optical sample paths having different lengths, such that information relative to portions of the sample at different depths can be collected.

Abstract: The invention concerns a quantitative phase-contrast digital holography method for the numerical reconstruction of images, comprising the following steps: A. acquiring a digital hologram of an investigated object; B. reconstructing the digital hologram in a reconstruction plane; C. reconstructing the complex field for the digital hologram; D. obtaining the phase map starting from the complex field; the method being characterised in that it further comprises the following steps: E. applying to the digital matrix of any step A, B, C a shear sx and/or sy respectively along directions x and/or y; F. subtracting the matrix obtained in step E from the starting matrix of step E, or vice versa; G. integrating the obtained matrix along directions x and/or y; H. calculating at least a defocus aberration term; I. subtracting said at least a term calculated in step H from the matrix obtained in step G, the steps G to I being subsequent to step D.
