Considerations of Television Holography
暂无分享,去创建一个
Television holography systems are considered with particular emphasis on the resolution requirements of the camera and reproducer. Methods are shown whereby conventional cameras and reproducers can be efficiently used at real-time scan rates. The spatial frequency requirements for the camera are minimized by using an on-axis reference wave. This wave is shifted in frequency or phase so as to create a signal that allows for the separation of the desired image terms.
