Description

Optical Engineering publishes papers reporting on research and development in optical science and engineering and the practical applications of known optical science, engineering, and technology. Papers should describe the original work of the authors that has not been previously published in a refereed journal. Papers should be substantial and significant in content. Contributed papers cover a broad range of subject classifications encompassing the general fields of optical design and fabrication, lasers, astronomy, remote sensing, industrial inspection and processing, optical physics and chemistry, x-ray optics, integrated optoelectronics, microlithography, fiber optics, imaging and image processing, holography, signal processing, high-speed photography, medical optics, and electro-optical systems. In addition to contributed research papers, Optical Engineering often includes special sections of papers in key areas of technology. Special sections are assembled by guest editors.

    ABSTRACT: The question concerning stability of a fundamental Bessel beam propagated in a turbulent atmosphere is considered. In this study, features of the spatial structure of distribution of the mean intensity of a fundamental Bessel beam in a randomly inhomogeneous medium are analyzed in detail. Features of the propagation of an optical Bessel beam in a turbulent atmosphere are studied on the basis of the secondorder mutual coherence function of the field of an optical beam by using the extended Huygens–Fresnel principle. A condition has been derived for the mean intensity of a Bessel beam, which is a quantitative criterion for the formation of a beam along a long path in a turbulent atmosphere.

    ABSTRACT: An appearance of the photoluminescence anisotropy induced by photochemical reaction under continuous irradiation with polarized light is demonstrated for an ensemble of CdSe/ZnS quantum rods chaotically embedded in the pores of filter paper. A specific relaxation of the photoinduced anisotropy is revealed in darkness after an extended period of irradiation. This process is attributed to rotational diffusion of the nanocrystals in the pores of filter paper. The suggested theoretical model is used to estimate the rotational diffusion constant D , which is calculated to be 9.7×10 −3 s −1 for the sample after 5 h of irradiation.

    ABSTRACT: In this study, a theoretical model of embedded fiber Bragg grating sensors was developed to provide predictions of the strain transfer rate and average strain transfer rate without the assumption that the host material is subjected to uniform axial stress. Further, a finite element (FE) analysis was performed to validate the present model. It was shown that the theoretical results with the present model are in good agreement with those by FE analysis. Finally, the parametric analysis was used to quantitatively investigate the effect of the parameters of the adhesive layer and host material on the strain transfer rate and average strain transfer rate.

    ABSTRACT: The evolution of Stokes generation up to the n’th stage and the analytical solutions of commonly used Raman equations including numerical simulation and experimental results is reported. For the experimental work, a 1-km un-doped single-mode fiber was pumped with an ytterbium-doped fiber laser system (FL) in CW regime at 1064 nm in a free running configuration. We showed that it is possible to obtain up to the N’th power thresholds and maximum power for each Stokes by using compact analytical solutions as a first approximation in an arguably simple, quick process.

    ABSTRACT: We present the implementation and validation of low-coherence Fabry–Perot interferometer for refractive index dispersion measurements of liquids. A measurement system has been created with the use of four superluminescent diodes with different optical parameters, a fiber-optic coupler and an optical spectrum analyzer. The Fabry–Perot interferometer cavity has been formed by the fiber-optic end and mirror surfaces mounted on a micromechanical stage. The positive result of the validation procedure has been determined through statistical analysis. All obtained results were 99.999% statistically significant and were characterized by a strong positive correlation (r>0.98). The accuracy of the measured result of implemented low-coherence Fabry–Perot interferometer sensor is from 83% to 94%, which proves that the sensor can be used in the measurement of refractive index dispersion of liquids.

    ABSTRACT: A noninterferometric technique used to measure the diffusion coefficients of transparent liquid solutions is reported. This technique uses a white light source and a diffusion cell, with an artificially developed fringe pattern of dark and white stripes at its entrance. As the diffusion process takes place in the cell, the light passing through this nonuniform refractive index medium will bend toward the higher refractive index region, which results in a fringe shift. This shift in the fringe pattern at different times is recorded in a personal computer (PC) using a CCD camera for the calculation of diffusion coefficients. The fringe shift is calculated after skeletonization and linear fit of the captured fringe system. The diffusion coefficient of different concentrations of ammonium dihydrogen phosphate was determined using the proposed technique and the measured values lay within 1% of the reported values. Detailed theoretical and experimental analyses with a comparison of other existing results are discussed.

    ABSTRACT: We present an analytical model for a generic two-wave directional coupler, in the conceptual frame of coupled single-mode planar (slab) waveguides. The modal relation of dispersion is expressed exactly under a matrix form. In the simplest symmetric configuration, the lift of degeneracy between the propagation constants of the even (slow) and odd (fast) supermodes is the exact image of the coupling constant.

    ABSTRACT: We present a bitstream decoding processor for entropy decoding of variable length coding–based multiformat videos. Since most of the computational complexity of entropy decoders comes from bitstream accesses and table look-up process, the developed bitstream processing unit (BsPU) has several designated instructions to access bitstreams and to minimize branch operations in the table look-up process. In addition, the instruction for bitstream access has the capability to remove emulation prevention bytes (EPBs) of H.264/AVC without initial delay, repeated memory accesses, and additional buffer. Experimental results show that the proposed method for EPB removal achieves a speed-up of 1.23 times compared to the conventional EPB removal method. In addition, the BsPU achieves speed-ups of 5.6 and 3.5 times in entropy decoding of H.264/AVC and MPEG-4 Visual bitstreams, respectively, compared to an existing processor without designated instructions and a new table mapping algorithm. The BsPU is implemented on a Xilinx Virtex5 LX330 field-programmable gate array. The MPEG-4 Visual (ASP, Level 5) and H.264/AVC (Main Profile, Level 4) are processed using the developed BsPU with a core clock speed of under 250 MHz in real time.
