Abstract

A polarimeter can be constructed using a document camera as a visualizer and a standard smartphone screen as a source of polarized light. A pair of 3D glasses can be used as a polarizing filter and the optical rotation angle of liquids can be measured using any free compass app. Consequently, a demonstration of optical rotation can be conducted with no preparation time or specialized equipment.
