Latest Patents

One of Greenaway's latest patents is titled "Method of, and apparatus for, determination of position in ultrasound imaging." This invention involves a method for determining the position of a target using a metric. It comprises receiving multiple ultrasound signals that represent energy from the target. For each of several different foci, the ultrasound signals are adjusted based on the focus, allowing for the determination of a value of the metric using these adjusted signals. The method further utilizes the determined values for the metric across different foci to ascertain the target's position.

Another significant patent is "Systems and methods of phase diversity wavefront sensing." This invention features a phase diversity wavefront sensor that includes an optical system with at least one optical element for receiving a light beam. It also incorporates a diffractive optical element with a pattern that defines a filter function. This setup produces images from the light beam associated with at least two diffraction orders. A detector is employed to detect these images and output corresponding image data. The system is designed to provide telecentric, pupil plane images of the light beam, and a processor executes a Gerchberg-Saxton phase retrieval algorithm to measure the wavefront of the light beam.
