Latest Patents

Nguyen holds a patent for "Gradient light interference microscopy for 3D imaging of unlabeled specimens." This patent describes a system and methods for quantitative optical phase imaging of a sample. The process involves generating first and second replica fields characterized by respective optical phases, which are cross-polarized and shifted in a direction transverse to the sample's surface. The replica fields undergo Fourier transformation, and the second replica field is retarded by four successive phase shifts. After inverse Fourier transforming, both fields pass through an analyzer polarizer, allowing for the superposition of the fields on a detector array to create four successive detector signals. These signals are then solved to derive a gradient of the optical phase of the image field, which can be integrated to obtain a quantitative phase image.
