Abstract

We demonstrate that polarized light is maintained differently in densely packed versus dilute suspensions of polystyrene microspheres. The degrees of linear and circular polarization were measured versus scatterer concentration in aqueous suspensions of 0.48-, 0.99-, 2.092-, and 9.14µm-diameter polystyrene microspheres. The results indicate that, for dilute suspensions of microspheres where independent scattering is assumed, the degrees of linear and circular polarization decrease as the scatterer concentration increases. For dense suspensions, however, the degree of polarization begins to increase as the scatterer concentration increases. The preferential propagation of linear over circular polarization states in dense suspensions is similar to results seen in biological tissue.

Experimental setup, consisting of a He–Ne laser, a chopper operating at 2.78 kHz, polarizing elements for the light that is incident upon the sample, a variable-wave plate (VWP), a photoelastic modulator (PEM) operating at 50 kHz, a linear polarizer (LP), a photodetector, and a lock-in amplifier. The maximum degree of polarization with no sample present was 1.0001.

Each point is an average of three measurements. The error bars represent the standard deviation; points without visible error bars have errors that are smaller than the symbol.
