Noise robust phase unwrapping with a virtual pyramid

getimage

Now, it is possible to effectively unwrap phase with noisy and low-signal interferometric measurements with the new method of phase unwrapping called the virtual pyramid wavefront sensor. This was demonstrated while reconstructing wavefronts from interferograms obtained in a digital (SLM-based) phase-shifting point diffraction interferometer. In comparison with existing methods, this new phase unwrapping method was found to be robust to random noise. We believe that this method can be applied to several metrology applications in ophthalmology, magnetic elastography and astronomy.

Reconstructing full crystalline lens shape in vivo using OCT imaging, published in IOVS

imagen8

We developed a methodology to reconstruct the entire crystalline lens shape, beyond the area visible through the pupil. The method uses data from ex vivo crystalline lenses to develop, test and validate the model. The accuracy in the estimation of lens volume, lens diameter or the equatorial lens position exceeds that achieved by state-of-the art methods. The method was applied in vivo in accommodating and cataract eyes. The paper is published in IOVS (Special issue commemorating 25 years of OCT)
