- Basic Study on Creation of Invisible Shadows by Using Infrared Lights and Polarizers

Abstract:
This paper proposes a method for hiding information inside of an actual object and viewing the hidden information as shadows selec- tively by rotating the object. Our proposed system creates shadows by using the properties of the polarizing plates and the 1/2 wave- length boards. The goal of our research is to realize a novel method of information hiding.
