A direct linear mapping exists between these quantities and the elements of the Wolf coherency matrix, with the first of these quantities corresponding to that matrix's trace.
A direct linear mapping exists between these quantities and the elements of the Wolf coherency matrix, with the first of these quantities corresponding to that matrix's trace. An alternative to the use of these quantities is the use of a matrix that contains eight independent parameters. These quantities can be obtained by reformulating the time-varying field as the equation of a Lissajous figure and then performing a time-average. These quantities are used to define the Poincare sphere and a vector constructed from these quantities is manipulated by multiplication with the Mueller matrix; that operation is complementary to the Jones calculus. The first of these quantities represents intensity, and these quantities are all quadratic in the field strength. Often denoted I, Q, U, and V, for 10 points, identify these numbers which describe a light wave's degree of polarization.
