Latest Patents

Wanli Chi's latest patents include groundbreaking technologies such as an optical element, device, method, and applications involving a novel phase-coded aperture. This invention features an optical imaging system that utilizes a coded-aperture followed by a detector array, which is complemented by an image processor. The system is designed to form a diffraction pattern on the detector array when focusable radiation from a point source is modulated by the coded-aperture's transmission function. An iterative phase retrieval method is employed to calculate the phase-coded aperture transmission function, allowing for effective image recovery through correlation-type processing.

Another notable patent involves an extended depth of field achieved through a computational imaging system. This system combines a multifocal imaging subsystem that produces a blurred intermediate image with a digital processing subsystem that recovers an image with an extended depth of field. The multifocal imaging system is characterized by spherical aberration, which serves as the primary feature of the purposeful blur. The central obscuration of the multifocal imaging subsystem enhances the uniformity of point-spread functions across various object distances. An iterative digital deconvolution algorithm is utilized to convert the intermediate image into a recovered image, incorporating a metric parameter that accelerates convergence and improves image quality.
