Latest Patents
One of his latest patents is titled "Complex diversity for accurate phase retrieval with single shot acquisition." This innovative concept provides a new diversity approach for achieving precise phase retrieval using a single shot acquisition. The method involves obtaining multiple irradiance data through a diffractive grating or computer-generated holography (CGH) designed to produce various diffraction orders with distinct diversity values. The effective filters associated with each diffraction order are calculated, incorporating both real and imaginary values that represent absorption and phase shift across the filter plane. This reconstruction process relies on a thorough understanding of the effective filters for each diffraction order, ensuring high-quality reconstruction of the extrinsic phase.
Another notable patent is the "Aberration estimating method, aberration estimating apparatus, and storage medium." This method entails acquiring a light intensity distribution of an optical image formed by a target optical system. It includes estimating the aberration of the optical system based on this distribution, determining an initial aberration value, and refining the estimation using this initial value. This process is crucial for improving the performance of optical systems.
