全息摄影自1948年由D.Gabor提出以来,取得了飞速的发展,在高速摄影领域中也获得了广泛的应用,一般认为,全息摄影包括全息干涉订量。全息摄影的主要优点是:可在平面全息图上获得目标的三维立体象,可以极大地提高目标象的信息量;可用黑白底片获得目标的彩色三维象,全息干涉计量能简单地获得目标的三维干涉图,且能实时地在整个体积中测量光学的非均匀性和密度分布。
Holographic photography has been developed rapidly since it was put forward by D. Gabor in 1948. It has also been widely used in high-speed photography. It is generally believed that holography includes holographic interferometry. The main advantages of holography are: the three-dimensional object can be obtained on a planar hologram, which can greatly improve the information amount of a target image; a color three-dimensional image can be obtained by using a black and white film, and the holographic interference measurement can simply obtain the target three- Interferograms and can measure optical non-uniformity and density distribution throughout the volume in real time.
