Latest Patents

Ying Xu's latest patents include a "Method and system for tomographic projection correction." This invention involves measuring the position of a sample to correct for any off-axis motion during tomography using an x-ray projection microscope system with a rotation stage system. The position is sensed using a precision-machined, low-CTE gold-coated cylinder or disc and three to five capacitive distance sensors. The correction is performed purely as image processing in software, applying an appropriate shift in X and Y of the captured x-ray projections. Calibration is often necessary for each system to account for any machining errors or positioning errors of the capacitive sensors, and this calibration should be repeated whenever maintenance is performed on the metrology setup.

Another significant patent is the "Alignment assembly," which is used to center a sample on a moving stage system. This assembly includes a pair of slides stacked on a stage with linear perpendicular movement relative to each other, along with at least one actuator that is physically separate from the linear slides and stage. The actuator(s) extend an actuator arm to move the linear slides and retract the arm for subsequent movement of the stage during and after the process of centering the sample in two dimensions.
