RT Book, Section T1 Introduction to gyrator transform A1 Alieva Krasheninnikova, Tatiana A1 Rodrigo Martín-Romo, José Augusto A1 Calvo Padilla, María Luisa AB We introduce the gyrator transform which produces a rotation of two-dimensional signal in phase space. Main properties of this transform are considered. The flexible optical set up for gyrator transform experimental implementation is discussed. The applications of the gyrator transform to image processing such as filtering, noise reduction, encryption are demonstrated.
