Imaging of virtual objects with a plane periodic grating.
The purpose of this study is to let a plane periodic grating act as an imaging element for general objects. Using the Fresnel approximation and the Kirchhoff diffraction theory, we investigated an object wave diffracted by a grating. We demonstrated that an image of an original virtual object can be produced by the nth-order monochromatic diffracted wave of a grating. The impulse response of this imaging system and some imaging properties of this imaging system were obtained.
