Latest Patents

One of Liu's latest patents is a "Rotational stage for high speed, large area scanning in focused beam systems." This invention features a mechanical scanning stage designed for high-speed image acquisition in focused beam systems. The innovative design consists of four stages: the first stage provides linear motion, the second stage offers rotational positioning, the third stage is movable in a first linear direction, and the fourth stage is positionable in a second linear direction orthogonal to the first. These four stages work together, responding to input from a controller programmed with a polar coordinate pixel addressing method. This allows for precise positioning of a specimen mounted on the mechanical stage, enabling an applied static focus beam to irradiate selected areas of interest, which are then imaged by collecting signals from the specimen.
