A computationally efficient method for image registration is investigated that can achieve an improved performance over the traditional two-dimensional (2-D) cross-correlation-based techniques in the presence of both fixed-pattern and temporal noise. The method relies on transforming each image in the sequence of frames into two vector projections formed by(More)
A statistical algorithm has been developed to compensate for the fixed-pattern noise associated with spatial nonuniformity and temporal drift in the response of focal-plane array infrared imaging systems. The algorithm uses initial scene data to generate initial estimates of the gain, the offset, and the variance of the additive electronic noise of each(More)

A comprehensive study of reliability failure modes in an advanced through-silicon via (TSV) mid process flow is presented in Part I of this paper. This is the first time unique TSV mid reliability failure modes at leading-edge TSV dimensions have been observed and reported. TSV Kelvin, comb and chain test structures with 10:1 aspect ratio and a TSV diameter(More)
Space Surveillance Telescope (SST) is a Defense Advanced Research Projects Agency (DARPA) program designed to facilitate the detection of space debris in earth's orbit. In order to achieve optimal performance, focusing of the telescope can be conducted by retrieving phase information in the image to determine the amount of defocus and then moving the(More)
1. ABSTRACT A laser-illuminating imaging system operating in the presence of atmospheric turbulence will encounter several sources of noise and diffraction induced errors that can make postprocessing the images difficult. As the beam propagates, turbulence induced tilt will cause the beam to wander off axis from the target. This is especially troublesome in(More)
