Characterization of 3-5 micron thermal imagers and analysis of narrow band images
(Monterey California. Naval Postgraduate School, 2004-12)
In this study, the use of multi narrow-band filters was explored to correlate or fuse information to improve detection and recognition for specific targets of interest. To fully understand the viability and limitations of ...
Detecting near-UV and near-IR wavelengths with the FOVEON image sensor
(Monterey California. Naval Postgraduate School, 2004-12)
Traditionally, digital imaging systems rely on the use of dedicated photodetectors to capture specific wavelengths in the visible spectrum. These photodetectors, which are commonly made of silicon, are arranged as arrays ...
Alternate configurations for blocked impurity band detectors
(Monterey California. Naval Postgraduate School, 2004-12)
Silicon Blocked Impurity Band (BIB) detectors are highly efficient, radiation-hardened photodetectors that operate in the range of 5-40 æm. To further extend BIB coverage to 40-350 æm, Ge and GaAs BIB detectors are under ...
High responsivity tunable step quantum well infrared photodetector
(Monterey, California. Naval Postgraduate School, 2004-12)
In this thesis, the performance of a step quantum well infrared photodetector (QWIP), which was designed to detect a laser spot at 1.05 m æ and IR radiation between 9.5 m æ to 10.5 m æ, was evaluated. In the far infrared ...
Infrared characterization of SiN films on Si for high speed electronics applications
(Monterey California. Naval Postgraduate School, 2004-12)
In this thesis, SiN films grown on Si substrates were characterized using Fourier Transform Infrared (FTIR) spectroscopy. The stress in SiN films can be used to enhance of mobility of electrons and holes which increases ...
Evaluation of night vision devices for image fusion studies
(Monterey California. Naval Postgraduate School, 2004-12)
Night Vision Devices (NVD) using Image Intensification (II) technology are among the most important sensors used by ground troops and aviators in night operations for modern combat. With the intensified images from these ...
A low-cost man-portable free-space optics communication device for Ethernet applications
(Monterey California. Naval Postgraduate School, 2004-12)
This thesis sought to design and implement a low-cost, portable, Free-Space Optics (FSO) communications device for Ethernet applications. Under some circumstances such a device would have utility at a Combat Operations ...
Design of two-axis capacitive accelerometer using MEMS
(Monterey California. Naval Postgraduate School, 2004-12)
MEMS technology is rapidly taking an important role in today's and future military systems. MEMS are able to lower the device size from millimeter to micrometer and maintain and sometimes surpass the performance of ...
A novel approach to modeling the effects of radiation in Gallium-Arsenide solar cells using Silvaco's atlas software
(Monterey, California. Naval Postgraduate School, 2004-09)
The effects of radiation in GaAs solar cells has been extensively researched and the results of numerous investigation have yielded a considerable amount of information about the degradation in irradiated solar cells. This ...
Infrared face recognition
(Monterey, California. Naval Postgraduate School, 2004-06)
This study continues a previous face recognition investigation using uncooled infrared technology. The database developed in an earlier study is further expanded to include 50 volunteers with 30 facial images from each ...
