Latest Patents

One of his latest patents is the "Information-efficient spectral imaging sensor." This invention features a programmable optical filter designed for multispectral and hyperspectral imaging. The filter effectively splits light collected by an optical telescope into two channels for each pixel in a scanned image. One channel manages the positive elements of a spectral basis filter, while the other handles the negative elements. Each channel disperses light into multiple spectral bins, with attenuation based on the spectral basis vector's values. This innovative system allows for efficient optical determination of target presence, contrasting with conventional data-intensive hyperspectral imaging systems.

Another notable patent is the "Near field optical probe for critical dimension measurements." This invention utilizes a resonant planar optical waveguide probe to measure critical dimensions on objects at 100 nm and below. The optical waveguide features a central resonant cavity flanked by Bragg reflector layers. Light from a narrow bandwidth laser source resonates in the cavity, creating an evanescent electrical field. As the object with measurable structures is translated past the cavity, variations in the intensity of the light occur due to refractive index contrasts. This allows for precise determination of the structures' topography.
