Physical Significance of the Determinant of a Mueller Matrix

Abstract

The determinant of a Mueller matrix M plays an important role in both polarization algebra and the interpretation of polarimetric measurements. While certain physical quantities encoded in M admit a direct interpretation, the understanding of the physical and geometric significance of the determinant of M (detM) requires a specific analysis, performed in this work by using the normal form of M, as well as the indices of polarimetric purity (IPP) of the canonical depolarizer associated with M. We derive an expression for detM in terms of the diattenuation, polarizance and a parameter proportional to the volume of the intrinsic ellipsoid of M. We likewise establish a relation existing between the determinant of M and the rank of the covariance matrix H associated with M, and determine the lower and upper bounds of detM for the two types of Mueller matrices by taking advantage of their geometric representation in the IPP space.

Quantum Cryptography Experiment using Optical Devices

“…A HWP that is installed on a rotator and will be rotating at a random angle decided upon by Alice and Bob is also included. Given that the Stokes vector has four dimensions, Mueller matrices, as shown by [20], can be used to characterize the optical components of the HWP device as four by four matrices. The HWP operation's rotation is shown as [21]: www.ijacsa.thesai.org Fig.…”

Mueller Matrix Polarizing Power

“…There are certain well-known descriptors that can be derived from the Mueller matrix M and provide information on specific features related to enpolarizing (diattenuation and polarizance [1][2][3][4][5][6]), depolarizing [7][8][9][10][11][12][13][14][15][16][17][18][19], retarding [8,20,21] and other properties [22,23].…”
