Analysis of imaging characteristics of parallax images in double diffraction grating imaging

Abstract The relation between the imaging characteristics of parallax images (PIs) and the system parameters of the double diffraction grating (DDG) imaging system is analyzed. DDG imaging method may produce parallax images (PIs) efficiently. However, a geometrical analysis is required to improve the applicability of the imaging system. The system parameters considered include the wavelength of light source, the spatial resolution of the diffraction grating, and positions of diffraction gratings and an imaging lens. The imaging characteristics of the DDG imaging defined and described in terms of positions and parallax angles of PIs. The ray-optical analysis is performed for the explanation of the imaging characteristics.
