PDF: 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 selectively 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.
