An implicit finite--difference (IFD) scheme is introduced for solving the parabolic equation representing electromagnetic wave propagation in the troposphere. Using Box method, the fading to the electromagnetic wave is calculated especially when the modified refractivity varies both with the range and the height in the representative atmosphere conditions. The consistency, stability and convergence of the Box method is demonstrated.

Our goal for the CD metrology process is to understand the influence of defocus and illumination latitude upon measured CDs and to optimize the focus and illumination settings for smallest measured CD range. For consistent submicron optical metrology process, the measured CD range should be better than +/- 10 nm (6S). The defocus and illumination latitudes are generated when the features are measured through focus at different illuminations. The process step is the factor that sets the conditions for different illumination modes. Traditional illumination modes in mask metrology are transmitted and reflected. The confocal reflected illumination mode adds a new dimension to the standard reflected light because of the increase in both transversal and longitudinal resolutions. The combined illumination between transmitted and reflected confocal modes proposed here, provide increased feature edge gradient and decreased intensity background noise. To emphasize the effects of the illumination modes, an algorithm is developed for CD metrology optimization using traditional and combined illumination techniques.

A basic class of structuring-element pairs for segmentation-free character recognition via the morphological hit-or-miss transform is developed for Courier font. Both hit and miss structuring elements are sparse and they are selected so that the hit-or-miss transform can be applied across the test image without prior segmentation. Besides being able to achieve high rates of accuracy on text with touching characters, the hit-or-miss algorithm, as developed herein, is shown to be very robust with respect to the threshold level for the input gray-scale data.

Interferometry 94 - New Techniques and Analysis in Optical Measurements Conference

Neural networks are being increasingly used in the visual pattern recognition field. They have already been applied with some success to such problems as the classification of fingerprints, the recognition of facial expressions and the identification of hand-written characters. This would suggest the possibility of applying a neural network system to the conceptually similar field of interferometric fringe analysis. Although the algorithmic techniques of phase stepping and Fourier fringe analysis have been successfully applied to many fringe analysis problems, there exist some areas, notably with complicated and noisy images, where a different approach may be required. Here, the backpropagation paradigm is applied to two simple fringe analysis problems. Firstly, to find the radius of a one dimensional curved surface from its simulated intensity distribution. Secondly, to identify four lens shaped objects of different radii of curvature from fringe patterns obtained under different conditions. Both cases were met with reasonable success, but the overall implications of the results were that, when applied to fringe analysis, neural networks would function more successfully at identification, rather than precise measurement.

In recent years design concepts for diffractive elements which can be used in the paraxial domain of diffractive optics has dominated the literature. We present a design concept for periodic and non-periodic structures which is embedded in the design theory of diffractive elements. It is suitable for diffractive elements having continuous or multilevel profiles with optimized diffraction efficiency. This paper is based on reference.

Microbend losses have been used as the transduction mechanism in intensity modulated optical fiber sensors for the measurement of various physical variables such as pressure, strain, temperature, acceleration, magnetic, and electric fields 1-4. These sensors are attractive for the industrial sector because of their robust construction and simple signalprocessing techniques.

Monte Carlo simulation technique is used to study photon migration in biological tissues. On a 36 mm diameter cylinder, temporal point spread function is simulated for each of the seven detectors around the model. Information such as mean-time-of-flight, differential pathlength factor, and detected photon number are recorded. Two back-projection algorithms have been proposed to reconstruct tomographic images of phantom.

This paper considers target detection with SAR and coherent subtraction. We shall show with experimental data that the coherent subtraction technique may be used to suppress outliers and obtain approximate Gaussian distributions for clutter and noise. We shall also derive generalized likelihood ratio (GLR) detection algorithms that may be used with SAR images that are obtained with coherent subtraction. We shall analytically compare the performance of (a) a single pixel detector, (b) a detector using complete knowledge of the target signature information and known orientation information, (c) a detector using incomplete knowledge of the target signature information and known orientation information, (d) a detector using unknown target signature information and known orientation information, and (e) a detector using unknown target signature information and unknown orientation information.

In situ measurements of optical properties made from a ship can be biased by the ship's shadow. In an effort to evaluate the ship shadow perturbation created by the R/V Weatherbird II, profiles of downwelling irradiance, E_d(z,(lambda) ), upwelling radiance, L_u(z,(lambda) ), as well as derived apparent optical properties (AOPs) were obtained at distances of 1, 3, 6 and >= 20 m off the ship's stern. Two statistical analyses are explored here. The first compares the mean difference between simultaneously obtained fluxes and AOPs sampled at distances greater than 20 m from the ship to those taken 1 and 6 m off the stern. The second analysis compares derived AOPs taken at each of the four distances throughout the length of the experiment. Only rarely are significant differences found for data beyond three meters off the ship's stern; however at 1 m off the stern significant discrepancies are intermittently observed. This work illustrates that the inherent sources of noise in determining fluxes and AOPs in the upper ocean are generally greater than the effects incurred by the ship's own shadow under optimal conditions.

Image texture plays a vital role in the segmentation process. A novel unsupervised segmentation approach based on multiresolution cooperative texture model computation is developed. The multiresolution segmentation approach is based on the observation that the human visual system utilizes relatively `global' information about an image in conjunction with `local' information to reach segmentation decisions. The texture model developed is based on sets of gray level co-occurrence matrices rather than measures extracted from them. The concept of multiresolution associated region (MAR) is developed for pyramid schemes. The other algorithmic constituents for the segmentation scheme such as normalized match distances between texture models, region homogeneity criteria with extensions to MARs, are systematically developed. The MAR aggregation rule is utilized to perform segmentation decisions at the base resolution level. The segmentation strategy was tested extensively on natural texture mosaics as well as on real scenes and the results are analytically presented. An important observation was that smaller texture models at multiple resolutions performed better than a very large texture model at single resolution.
