How to observe the difference between left and right rotation intensity of chiral circularly polarized light

I have prepared chiral circularly polarized luminescent materials based on liquid crystal. The luminescence asymmetry factor(g lum) measured by the circular polarization spectrometer is in the order of 10^-1. However, the difference in light intensity cannot be viewed by the naked eyes under the left/right-handed polarizer. Is there any way to directly observe the difference of left- and right-handed circularly polarized light intuitively (for examples, using designed optical filter or enhance the excitation)?

AFAIK, almost all solid-state optical detectors can measure a 10% difference in intensity really easily.

However, the difference in light intensity cannot be viewed by the naked eyes under the left/right-handed polarizer.

Can you chop between the two different sources to see if your eye can then detect the 10% difference? You could chop at about 1Hz or so at first, and then try faster if that makes the difference more obvious.
