Underwater acoustic interferometer

1970 IEEE International Conference on Engineering in the Ocean Environment - Digest of Technical Papers, 1970

Measurements have been made showing the limitations a seawater medium imposes on the resolving power of underwater acoustic equipment. An interferometer was designed that is capable of measuring the "visibility"' of the interference fringes in the far field of an acoustic radiator. Phase and amplitude fluctuations of the divided acoustic wavefront are analyzed utilizing correlation techniques.

We consider the popular spatial smoothing technique and show via the covariance matrix eigenvalue analysis that the simple suboptimal rule for choosing of the subarray size exists in a practically important situation of two coherent equipower closely spaced sources. This rule has been derived by maximizing the distance between the signal subspace and the noise subspace eigenvalues of spatially smoothed ...

  • Influence of the spatial coherence of the background noise on high resolution passive methods

    Research directed towards the improvement of underwater passive listening technique has led to powerful methods but which require the knowledge of the spatial coherences of the sources and of the background noise. They are sensitive to the shape of the wavefront of the signals from the sources. But they are also sensitive to the spatial coherence of the background noise : this is shown in this paper in particular for the method of the indentification of the components of the noisefield from the eigenvectors and eigenvalues of the spectral density matrix of the signals received on the array.

  • Fast and Accurate Collision Detection for Virtual Environments

    A realistic simulation system, which couples geometry and physics, can provide a useful toolkit for virtual environments. Interactions among moving objects in the virtual worlds are modeled by dynamic constraints and contact analysis. In order to portray the geometric interaction in a dynamical system or to simulate physical behaviors of entities in the virtual environments, it is essential to perform collision detection at interactive rate with minimal computation possible. In this paper, we present efficient algorithms for contact determination and interference detection between geometric models undergoing rigid motion. The set of models includes polyhedra and surfaces described by B-splines. The algorithms make use of temporal and spatial coherence between successive instances to reduce the number of pairwise tests and hierarchical data structures for checking overlaps between a pair of objects. Their running time is a function of the motion between successive instances. The main characteristics of these algorithms are their simplicity and efficiency. They have been implemented. A subset of these implementations, including I-Collide, RAPID and V-Collide are available as part of the collision detection packages at the UNC-CH website.

  • Far-Field Nonmodal Laser Emission for Low-Speckle Laser Projection

    In this letter, we discuss how the nonmodal emission regime's far field of a broad-area vertical-cavity surface-emitting laser (BA-VCSEL) can be used for low-speckle laser projection. A microlens beam homogenizer is used to exploit the low spatial coherence of the VCSEL's far field in the nonmodal emission regime. Using far-field instead of near-field illumination of the homogenizer has some important advantages for a practical projection system: the field emitted by the VCSEL can be directly projected onto the homogenizer without the need for additional lenses or accurate alignment. Speckle contrast values as low as 2.5% are measured and in good agreement with modeled contrast values.

  • Free electron lasers with sheet electron beams and two-dimensional planar Bragg resonators

    The use of two-dimensional Bragg resonators of planar geometry, realizing two- dimensional distributed feedback, is considered as a method of producing spatially coherent radiation from a large sheet electron beam. Selective properties of a 2-D Bragg resonator are studied when the transverse sides of the resonator are open and also when they are closed. A time-domain analysis of the excitation of an open 2-D Bragg resonator by a sheet electron beam demonstrates that a single mode steady-state oscillation regime may be obtained for a sheet electron beam of width up to 1000 wavelengths. At the same time, even in a closed 2-D Bragg resonator a steady-state regime can be realized if the beam width does not exceed 50-100 wavelengths. The project of an FEL with a 2-D Bragg resonator driven by a sheet electron beam based on the U-2 accelerator (INP RAS, Novosibirsk) is discussed.

  • Spatially incoherent random lasers for full field optical coherence tomography

    We demonstrate control of the spatial coherence of random laser emission by tuning the scattering strength and excitation volume. The optimized, spatially incoherent source is applied to full-field optical coherence tomography to mitigate crosstalk.

  • A cluster grouping technique for texture segmentation

    We propose an algorithm for texture segmentation based on a divide-and-conquer strategy of statistical modeling. Selected sets of Gaussian clusters, estimated via expectation maximization on the texture features, are grouped together to form composite texture classes. Our cluster grouping technique exploits the inherent local spatial correlation among posterior distributions of clusters belonging to the same texture class. Despite its simplicity, this algorithm can model even very complex distributions, typical of natural outdoor images.
