Latest Patents

One of his latest patents is titled "Simultaneous interrogation of multi wavelength-modulated fiber optical sensors by modulating an arrayed waveguide grating based demultiplexer." This invention describes a compact interrogator designed for the simultaneous interrogation of multi wavelength-modulated fiber optical sensors. It includes a planar waveguide-based demultiplexer that receives input signals from the sensors. An array of detectors is coupled to output waveguides of the demultiplexer, corresponding to different nominal wavelengths. A tuning element is utilized to match the nominal wavelengths of the output waveguide to the input signals from the respective sensors, allowing for the identification of the wavelengths of the individual sensors to be interrogated.

Another notable patent is "Full-field optical coherence tomography and its application to multiple-layer information decoding." This method involves extracting a tomographic image of a layer within a body using optical coherence tomography. It captures three images: a non-interference background image, a first interference-fringe image of the layer, and a second interference-fringe image that is phase-shifted relative to the first. The tomographic image is obtained by mathematically combining these three captured images. In a preferred embodiment, random noise is removed by averaging, and inter-layer effects are mitigated by applying a compensation function. This system is then employed to extract the 2D cross-sectional images encoded in a multiple-layer information carrier.
