Latest Patents

One of his latest patents is an optical apparatus that comprises an optical imaging arrangement generating either an image of the original object field or the field of the original sample at the pupil plane. This apparatus includes both amplitude and phase information. Additionally, it features a digital adaptive optics arrangement with a wavefront sensor and a computing unit. This setup is designed to generate at least one orthogonally translated digital copy of the original sample object field at the spatial Fourier or pupil plane. It also analytically calculates a wavefront error based on the phase difference between the original sample wavefront and its digital copy or copies.

Another notable patent involves systems and methods for sub-aperture based aberration measurement and correction in interferometric imaging. This patent describes systems and methods for sub-aperture correlation based wavefront measurement in a thick sample. It also includes correction as a post-processing technique for interferometric imaging to achieve near diffraction-limited resolution. The inventive technique can be applied to any coherent interferometric imaging technique and does not require knowledge of any system parameters. One embodiment of this application describes a fast and simple way to correct for defocus aberration, with a variety of applications for the method presented.
