Abstract

Adhesive tape is one of the most common material used to explain polarization of light yet its properties are often outlooked. Here, we measure the principal axis angle α and phase retardance β of an adhesive tape through the Mueller-Stokes formulation. A simple experimental setup was used consisting of two polarizers sandwiching the sample. Using a linearly polarized incident beam, the output intensity over the range of -90 to 90 degree analyzer orientation was detected to obtain the α and β values of quarter wave plate, adhesive tape, and acetate samples. We found that the tape is almost nonpolarizing at lengthwise orientation (α = 0.42°, β = 0.71°) but noticeable change is seen when it is rotated by 45° (α = 45.5°, β = 144.7°). The results of this study allow us to quantitatively describe the influence of various materials, especially the adhesive tape, in changing the polarization state of light.
