Spatial frequency sensitivity analysis of polarized light perception on the human macular with 3D Stokes vector

Abstract

This paper presents a matrix approach, developed using a 3D Stokes vector analysis, to simulate polarized light as perceived by the macular of the human eye, and views the human perception of polarized light as a multivariable applied optics problem then approached it in an analytical manner as a complex optical system. The objective is to give purpose and new understanding to a biomedical optical phenomenon. The approach is supported by simulated and experimental measurements. Based on the spatial sensitivity of the human eye, a Fourier transform-based spatial frequency sensitivity analysis of polarized images is performed. The approach uses the spatial frequency of the images and physical parameters of the macular to model and determine polarized images that elicit a heightened perception of polarization. An investigate is presented of the human perception of polarized grid images with lower and higher spatial frequencies against the perception of linear polarized images forming conventional Haidinger’s brushes. The approach paves the way for developing diagnostic images with improved perceived quality for patients vulnerable to macular degeneration.
