Optical coordinate transformations

Applied Optics, 1992
A novel technique for designing holographic optical elements that can perform general types of coordinate transformation is presented. The design is based on analytic ray-tracing techniques for finding the grating vector of the element, from which the holographic grating function is obtained as a solution of a Poissonlike equation. The grating function

A strict transformation from Cartesian to geodetic coordinates

Survey Review, 2008
An algorithm is derived to transform Cartesian coordinates to geodetic coordinates by employing ellipsoidal coordinates in an intermediate step. The algorithm is comparatively simple and stable in all steps for any point in space outside a geocentric ...

Closed-form transformation between geodetic and ellipsoidal coordinates [PDF]

Studia Geophysica Et Geodaetica, 2008
We present formulas for direct closed-form transformation between geodetic coordinates(Φ, λ, h) and ellipsoidal coordinates (β, λ, u) for any oblate ellipsoid of revolution.These will be useful for those dealing with ellipsoidal representations of the ...

Coordinates and coordinate transformations

1996
Abstract In the discussion of variational methods in the previous chapter we contrasted the Newtonian emphasis on the motion of particles with the Lagrangian idea of an invariant system property called the action, which has a stationary value under small arbitrary displacements of the coordinates and their associated velocities. Since

Transformation to Rotating Coordinates

Nature, 1970
IN the treatment of problems involving rotating coordinate frames one of two types of viewpoint is conventionally adopted. The assumption may either be made that the use of principles familiar in special relativity can be extended to the rotating coordinate case, or a general-relativistic treatment may be used, with use of an explicit coordinate ...

Coordinate transformations in object recognition.

Psychological Bulletin, 2006
A basic problem of visual perception is how human beings recognize objects after spatial transformations. Three central classes of findings have to be accounted for: (a) Recognition performance varies systematically with orientation, size, and position; (b) recognition latencies are sequentially additive, suggesting analogue transformation processes ...

Architectural Coordination of Enterprise Transformation

2017
Architectural coordination of enterprise transformation (ACET) integrates and aggregates local information and provides different viewpoints, such as financial, structural, or skill perspectives to the respective stakeholder groups, with the aim of creating a consensus and shared understanding of an enterprise transformation among the stakeholders. Its

Coordinate transformations, symmetries, and GHT

Proceedings of 3rd IEEE International Conference on Image Processing, 2002
A conjugate harmonic function pair is a suitable curvi-linear coordinate pair with which image iso-gray curves can be described. In this representation, images or parts of images which are symmetric with respect to such a function pair, have iso-gray curves which are lines or parallel line patterns. Detecting these lines, or generalized linear symmetry

Symbolic Representation of Coordinate Transformations

IEEE Transactions on Aerospace and Navigational Electronics, 1964
An analytical technique using a symbolic representation of the coordinate transformation for a rotation of axes is presented. The representation has the advantages of a signal flow diagram and yet retains the properties of a transformation matrix. A sign convention and the characteristics of the symbolic representation are defined.
