Latest Patents

Among his latest patents, the "Astigmatism Measurement Apparatus and Method Based on a Focal Plane" stands out. This invention involves a computer that receives image data from a star-shaped optical target situated in the object plane and calculates the angle-dependent boundary sharpness. The process includes generating the horizontal, x-direction, and vertical, y-direction, amplitude derivatives over portions of each star pattern image gathered from a Z panning sequence. A microscope slide stage moves the target vertically to capture images for detailed analysis. This method enables the detection of a distorted point spread function that varies along the optical axis, indicating the presence of astigmatism.

Another notable patent is the "Separation Apparatus and Method for Measuring Focal Plane." Similar to his previous work, this invention also utilizes a computer to analyze image data from star-shaped optical targets, employing a comparable technique for capturing and processing star pattern images. This innovation further enhances the precision in measuring astigmatism and contributes to the broader understanding of optical distortions.
