Abstract: | A new experimental method for measuring the optical anisotropy induced at photochemical reactions is proposed. The method is based on polarization holography and is a zero-background high sensitive technique. It is used to measure the molecular dichroism of fluorescein and the birefrigence induced at the additional photopolymerization of PMMA. |
