【摘要】 提出一种正-正两步法周视彩虹全息术,利用两次孔径共轭技术,勿需严格的共轭再现及复位对准过程,也不需要任何特殊成大口径的光学元件,便能获得可周视360°观察的平板彩虹全息图。更多还原

【Abstract】 A kind of two-step circular viewing rainbow holography with orthoscopic images is presented. A 360° circular viewing rainbow hologram recorded on a plane plate can be obtained by utilization of aperture conjugation technology two times. Here, the strict conjugation reconstruction and aiming process to replace the image are not necessary. Also, there is no requirement of particular or large aperture optical elements.更多还原
