Relationships between elements of the Stokes matrix
Applied Optics
|March 25, 2010
Summary
Stokes matrices, though having sixteen elements, are defined by four amplitudes and three phase differences. These relationships offer crucial consistency checks for experimental measurements of light scattering.
Area of Science:
- Optics
- Light Scattering
- Polarimetry
Background:
- Stokes matrices describe the polarization state of light.
- Sixteen elements define a Stokes matrix, derived from fundamental scattering amplitudes and phase differences.
- Relationships exist between these elements under specific scattering conditions.
Purpose of the Study:
- To explore the fundamental relationships between the elements of a Stokes matrix.
- To identify how these relationships change when considering ensembles of particles.
- To provide a framework for validating experimental polarimetry data.
Main Methods:
- Analysis of the mathematical structure of the Stokes matrix.
- Derivation of relationships based on scattering theory for single particles.
- Investigation of the impact of incoherent summation of Stokes matrices from particle ensembles.
Main Results:
- Nine independent relationships connect the sixteen elements of a Stokes matrix for single-particle scattering.
- For ensembles of particles, these relationships transform into six one-way inequalities.
- These inequalities serve as essential consistency checks for experimental data.
Conclusions:
- The inherent relationships within Stokes matrices are robust.
- The derived inequalities provide a powerful tool for verifying experimental measurements in polarimetry.
- This work simplifies the interpretation of complex scattering phenomena.

01:24Stokes’ Theorem and Its Applications
Stokes’ Theorem provides a fundamental connection between the circulation of a vector field along a closed boundary and the cumulative rotational behavior across the surface it encloses. For a smooth three-dimensional surface with an oriented boundary curve, this theorem offers a unified way to relate motion along the edge to local rotational effects distributed over the surface.Mathematical FormulationThe theorem states that the circulation of a vector field along a closed curve is equal to...
01:20Stokes' Law
Viscous forces, like friction, are intermolecular forces that resist the relative motion of molecules over each other. When a solid body moves through a liquid, viscous forces drag it in the opposite direction. The force's magnitude depends on the solid's shape and size, as well as its speed and the liquid's coefficient of viscosity, density and temperature.
The expression for the force on a solid spherical object in a fluid is called Stokes' law. Stokes' law is valid only for low Reynolds...

01:06Divergence and Stokes' Theorems
The divergence and Stokes' theorems are a variation of Green's theorem in a higher dimension. They are also a generalization of the fundamental theorem of calculus. The divergence theorem and Stokes' theorem are in a way similar to each other; The divergence theorem relates to the dot product of a vector, while Stokes' theorem relates to the curl of a vector. Many applications in physics and engineering make use of the divergence and Stokes' theorems, enabling us to write numerous physical laws...
01:21General State of Stress
The general state of stress within a material can be accurately depicted using a stress tensor. This tensor encapsulates the internal forces distributed within a material subjected to external forces or deformations.
Specifically, consider a tetrahedral element where one face, labeled XYZ, is perpendicular to the line OA, and the remaining faces align with the coordinate axes with point O as the origin. At any point, such as point O, the stress tensor can be used to determine the stress...

01:18Transformation of Plane Stress
Studying stress transformation is essential in understanding how stress components within a material, like a cube under plane stress, change with rotation. This change is analyzed by considering a prismatic element within the cube. As the element rotates, the stress components acting on it—both normal and shearing stresses—change in magnitude and orientation. This change is quantified using trigonometric functions of the rotation angle, relating the forces acting on the rotated element's faces...
01:20Relation between Mathematical Equations and Block Diagrams
In a spring-mass-damper system, the second-order differential equation describes the dynamic behavior of the system. When transformed into the Laplace domain under zero initial conditions, this equation can be effectively analyzed and manipulated. The transformation into the Laplace domain converts differential equations into algebraic equations, simplifying the process of isolating the output.
