Latest Patents

One of his latest patents is the Differential Polarization Interferometer. This device performs direct measurement of phase shifts of light waves passing through a sample composed of a transparent substrate with a thin deposited test film, specifically for metamaterial testing. The apparatus includes a laser source, a first polarizer, and two optically connected arms. The first arm generates orthogonally polarized components of a single output beam for a broadband non-polarizing beam splitter. The second arm features a controllable phase retarder to introduce a phase shift into one polarization component of the reflected single output beam, along with a second polarizer to equalize and mix the polarization components. This process transforms the reflected single output beam into a beam resulting from the interference of the polarization components. A photodetector then converts the intensity of this beam into an electric signal for output.

Another significant patent is the Surface Plasmon Resonance Sensor. This application involves a sensor utilizing a gold layer with embedded nanodiamonds, which employs surface plasmon resonance (SPR) to detect target molecules. This innovative approach enhances the sensitivity and specificity of molecular detection.
