Latest Patents

One of his latest patents is a "Method and apparatus for forming multiple images." This invention discloses a method and apparatus for forming multiple images of an object comprising a plurality of depth segments. An optical system includes an infinity optical subsystem and a multi-image optical subsystem. The infinity optical subsystem is designed to receive light from the object and form a first image focused at infinity. The multi-image optical subsystem receives the first image and forms multiple images via multiple focusing lenses. Each multiple image corresponds to a different depth segment, and a portion of the light from the first image can be filtered before entering a focusing lens. This allows for the formation of multiple images under different filtering conditions.

Another significant patent is the "Method and system for contactless fingerprint detection and verification." This invention provides a method for contactless fingerprint detection and verification by illuminating a fingerprint and directing reflected light through an imaging system using liquid crystal panels and birefringent elements to polarize the light. A plurality of polarized images are captured to calculate the depth of structural features on the fingertip. The invention also includes a means to generate a two-dimensional rolled equivalent image of the fingerprint for verification and authentication.
