We introduce a new scoring method for calculation of alignments of optical maps. Missing cuts, false cuts, and sizing errors present in optical maps are addressed by our alignment score through calculation of corresponding likelihoods. The size error model is derived through the application of Central Limit Theorem and validated by residual plots ...

Optical mapping of optically paced embryonic hearts
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013Conduction maps of early embryonic hearts with optical mapping point to heterogeneous conduction patterns that quickly evolve over time. In adult hearts, electrical pacing is utilized to determine the anisotropy of the conduction patterns and the susceptibility of the tissue to arrhythmias.

Optical Filtering of Aeromagnetic Maps
Applied Optics, 1974An optical processor has been used to filter aeromagnetic contour maps in order to obtain information on underground magnetic ore deposits. This was accomplished by directional filtering of the spatial Fourier transform of the contour map. The directional filtering yields maps of gradients having given directions.

An invisibility device should guide light around an object as if nothing were there, regardless of where the light comes from. Ideal invisibility devices are impossible, owing to the wave nature of light. This study develops a general recipe for the design of media that create perfect invisibility within the accuracy of geometrical optics.

Optical Contour Mapping of Surfaces
Applied Optics, 1973A precise nondestructive optical contour mapping method with adjustable sensitivity for noncontact testing of surface deformations up to 30 microm/cm is described. The method employs an optical grating that is placed in front of the test surface. Illumination of the grating by a monochromatic plane wave generates an interference pattern between the ...

Optical mapping of the atrioventricular junction
Journal of Electrocardiology, 2005In the normal heart, the atrioventricular node (AVN) is part of the sole pathway between the atria and ventricles, and is responsible for the appropriate atrial-ventricular delay. Under normal physiological conditions, the AVN controls appropriate frequency-dependent delay of contractions.

Potential mapping of optical tweezers
Optics Letters, 2011Optical tweezers are very often used for measurement of piconewton range forces. Depending on the displacement of the trapped bead, the trap may become stiffer which causes considerable underestimation of the measured force. We have shown, both by theory and experiment, that such a stiffening occurs for beads larger than 0.5 μm in radius. For the first

Intensity mapping optical aberrations
Applied Optics, 1978Intensity mapping aberrations for high average power laser beams are examined from the point of view of diffraction theory. For the Fresnel ripple aberrations, it was determined that indeed they behave like a circular diffraction grating where energy is diffracted into the far wings of the far-field intensity distribution without significantly ...

A Quantile Method for Sizing Optical Maps
Journal of Computational Biology, 2007Optical mapping is an integrated system for the analysis of single DNA molecules. It constructs restriction maps (noted as "optical map" ) from individual DNA molecules presented on surfaces after they are imaged by fluorescence microscopy. Because restriction digestion and fluorochrome staining are performed after molecules are mounted, resulting ...

Several potential applications of coherent optics in the field of topographic mapping have been identified.1 This paper outlines the motivation for applying coherent optics to topographic mapping, presents some additional applications not included in Ref. 1, and further discusses some applications developed in that reference.
