Latest Patents

One of his latest patents is titled "Methods for atmospheric correction of solar-wavelength hyperspectral imagery over land." This invention presents several improved methods for correcting atmospheric effects on remote images of the Earth's surface. The images consist of multiple simultaneously acquired images of the same scene, each containing numerous pixels at different wavelength bands, ranging from infrared to ultraviolet wavelengths. One method retrieves the aerosol/haze amount from an assumed ratio of in-band reflectances, rather than from an assumed reflectance value. Another method identifies cloud-containing pixels, enhancing the calculation of spatially averaged radiance and reflectance images in standard equations. Additionally, a method significantly reduces the number of mathematical operations needed to generate reflectance values by averaging water vapor and reflectance values over small groups of neighboring pixels. Furthermore, another innovative method accounts for shifts in wavelength calibration within the image, looping the calculation of parameters over a set of possible wavelength shifts and assigning the appropriate parameters to each pixel based on a pixel-location-dependent formula.

Another notable patent is for a "Surface contamination sensor." This ambient sensor includes a gas supply source that is energized before reaching the surface being sensed. It is capable of transferring energy to contaminants on the surface or vapor originating from them. The sensor detects optical emissions from the gas passed over the surface within a selected wavelength band characteristic of the contaminant's presence, indicating when such emissions are detected.
