The subject of this study is the design of a camera, which has maximum volume of 50 mm x 50 mm x 300 mm, using short infrared wavelength providing Rayleigh criteria. Firstly, the required flux per pixel has been calculated. Throughout these calculations, atmospheric losses have been obtained by MODTRAN program. Also signal to noise ratio has been examined at minimum and maximum integration time intervals. The focal length of the camera has been calculated as it receives 1 m resolution from 8 km distance. Moreover, the lens materials have been used as N-F2, LIF and BaF2 in this six lens system. The design has been done using ZEMAX optical design program and the performance of the system at focal plane was investigated by the help of Seidel aberrations, Modulation transfer Function (MTF), Spot diagram and Optical Path Difference (OPD) fan plot analyses.

INFRARED REFLECTIVITY SPECTRA OF TLGAS2-TYPE LAYER CRYSTALS
Hasanlı, Nızamı; RAGIMOV, AS; TAGIROV, VI; GUSEINOV, RE (Elsevier BV, 1982-01-01)
Infrared reflectivity spectra of TIGaS2, TIGaSe2 and TlInS2 layer crystals are measured for the polarization directions perpendicular and parallel to the optical c-axis in the spectral range from 20 to 400 cm-1. The optical dispersion parameters are obtained for both polarization directions. Besides, normal coordinates and effective force constants are determined for high-frequency lattice vibrations.
A numerical study on beam stability in eccentrically braced frames
Yiğitsoy, Gül; Topkaya, Cem; Department of Civil Engineering (2010)
A two-phase research program was undertaken numerically to assess the behavior of the beam outside of the link that is designed for overstrength of the link in eccentrically braced frames (EBFs). In the first phase, software was developed to conduct a statistical analysis of the typical cases designed according to the AISC Seismic Provisions for Structural Steel Buildings. In this analysis, it was noticed that most of the statistically analyzed cases do not satisfy the code requirement provided for overstre...
Shape Optimizations of Metallic Sheets for Improved Near-Zone Scattering, Reflection, and Focusing Characteristics
Altinoklu, Askin; Ergül, Özgür Salih (2017-10-12)
We consider full-wave analysis and optimizations of metallic sheets to obtain desired electromagnetic responses in the near-zone field intensity and power density distributions. Given a metallic sheet of finite size, deformations are applied to achieve diverse scattering and reflection characteristics, particularly focusing and collecting electromagnetic power at different locations. Optimizations are performed by employing genetic algorithms in a multigrid scheme on the discretized geometry, while each tri...
Beam Switching Reflectarray with MEMS Controls
Bayraktar, Omer; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2010-04-16)
This paper presents a 26.5 GHz beam switching reflectarray monolithically fabricated on glass substrate with the RF MEMS switches. The array is formed using 10x10 aperture coupled microstrip patch antenna (ACMPA) elements. RF MEMS switches are implemented on the transmission lines in order to sustain the beam switching. A prototype of a reflectarray with 90 RF MEMS switches is monolithically produced using an in-house surface micromachining process including the wafer bonding steps. The measurement result s...
Computer simulation of grain boundary grooving by anisotropic surface drift diffusion due to capillary, electromigration and elastostatic forces
Akyıldız, Öncü; Oğurtanı, Tarık Ö.; Department of Metallurgical and Materials Engineering (2010)
The aim of this study is to develop a theoretical basis and to perform computational experiments for understanding the grain boundary (GB) grooving in polycrystalline thin film metallic conductors (interconnects) by anisotropic surface diffusion due to capillary, electromigration and elastostatic forces. To this end, irreversible thermo–kinetics of surfaces and interfaces with triple junction singularities is elaborated, and the resulting well-posed moving boundary value problem is solved using the front–tr...
