Latest Patents

One of his latest patents is titled "Single shot full-field reflection phase microscopy." This invention relates to a full-field reflection phase microscope that combines low-coherence interferometry and off-axis digital holographic microscopy (DHM). The reflection-based DHM provides highly sensitive and single-shot imaging of cellular dynamics. The use of a low coherence source allows for depth-selective measurement, making it suitable for full-field measurement of membrane dynamics in live cells with sub-nanometer-scale sensitivity.

Another notable patent is "Distribution of refractive index measurement by synthetic aperture tomography." This invention focuses on systems and methods for quantitative three-dimensional mapping of refractive index in living or non-living cells, tissues, or organisms. It utilizes a phase-shifting laser interferometric microscope with a variable illumination angle. This technology enables tomographic imaging of cells and multicellular organisms, allowing for the quantitative characterization of specimen-induced aberrations in high-resolution microscopy.
