System identification approach applied to drift estimation

Author(s)
Tracy S. Clement, Frans Verbeyst, Rik Pintelon, Yves Rolain, Johan Schoukens
A system identification approach is applied to estimate the time base drift introduced by a high-frequency sampling oscilloscope. First, a new least squares

Metrics to Estimate Image Quality in Compressed Video Sequences

Author(s)
G O'Brien, S Israel, J Irvine, Charles D. Fenimore, John W. Roberts, Michelle Brennan, D Cannon, J Miller
A fundamental problem in image processing is to find objective metrics that parallel human perception of image quality. In this study, several metrics were

User-Oriented Evaluation of Compression for Motion Imagery

Author(s)
J Irvine, G O'Brien, J Miller, S Israel, Charles D. Fenimore, John W. Roberts, Michelle Brennan, Jeffrey Bartolucci, D Cannon
Motion imagery will play a critical role in future intelligence and military missions. The ability to provide a real time, dynamic view and persistent

Spectral decomposition of ultra-wide-band terahertz imagery

Author(s)
Erich N. Grossman, Charles Dietlein, Jonathan Chisum, A. Luukanen, J. E. Bjarnason, E. R. Brown
We investigate the spectral response of a THz imaging system based on ultrawideband cryogenic microbolometers. The bandwidth if this system, nominally 0.2 - 1.8

Broaband THz aqueous blackbody calibration source

Author(s)
Charles Dietlein, Zoya Popovic, Erich N. Grossman
We describe a broadband calibration source for the millimeter-wave to terahertz (THz) frequency range, the Aqueous Blackbody Calibration (ABC) source. The

Performance comparison of Nb and NbN antenna-coupled microbolometers

Author(s)
Charles Dietlein, A. Luukanen, J. S. Penttila, H. Sipola, L. Gronberg, H. Seppa, P. Helisto, Erich N. Grossman
We report the experimental results of a comparison between free-standing Nb and NbN microbolometer bridges coupled to equiangular spiral antennas on Si

TEM Calibration Methods for Critical Dimension Standards

Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, B Bunday, M R. Bishop, Michael W. Cresswell, J Allgair
One of the key challenges in critical dimension (CD) metrology is finding suitable calibration standards. Over the last few years there has been some interest

Recursive Motion Estimation of Range Image

Author(s)
Hamid Gharavi, Shaoshuai Gao
In this paper, we present an innovative recursive motion estimation technique that can take advantage of the in-depth resolution (range) to perform an accurate
