Polarization is well known and used in various optical applications to reduce unwanted reflections to a minimum while contrast is enhanced. For example, in photography, this effect is used to reduce glare from objects or to increase contrast in pictures. Undesired reflections can disturb detected images in complex applications when you have to identify different objects or to compare them to given parameters. With the use of polarizers, these unwanted reflections can be reduced to enhance the contrast and enable the application to work.
Cash handling machines
Everyone is familiar with this situation, you put a bank note in a vending machine and it is refused several times before the detection system can clearly identify it. Most of the time the reason for this behavior is unwanted reflexions. Paper money around the world is made of a lot of different materials to make it unique and difficult to counterfeit. The reflections of these materials are difficult to eliminate by optical detection systems and cause problems to identify and verify bank notes.
