Latest Patents
One of his latest patents focuses on calibration and error correction in multi-channel imaging. This innovative system calibrates by measuring geometric distortion in each sub-image, generating correction factors, and applying these factors to correct subsequent image data. Additionally, intensity transfer-function arrays are measured at each pixel to correct for system and detector nonlinearities and nonuniformity between images. The procedure is repeated over a range of wavelengths to produce a complete set of correction coefficients and transfer functions. When used for interferometric phase measurements, multiple measurements are taken, introducing a random phase offset in the reference path length at each measurement. The multiple phase data derived are then averaged to reduce phase-dependent systematic measurement errors.
Another significant patent involves a method and apparatus for restoring digitized video pictures generated by an optical height profiler while scanning a target surface. This method identifies regions of bad data and replaces erroneous height values with provisional height values selected from neighboring valid height values. Each provisional height value is assigned a position index corresponding to its proximity to the boundary of the region. Starting from the interior of the region, the technique replaces each provisional height value with a corrected height value calculated by interpolation of valid height values based on distance from the boundary as represented by the position indices. The resulting corrected height map is suitable for on-line visual display.
