How about the development of holography since 1970s?
Later, the new method of holographic recording information has been extended to infrared, microwave and sound waves.
In addition, a laser simulation calculation device is developed by using optical information processing method. With the cooperation of other technologies, it is used to deal with blurred images-identify features or improve clarity. The speed is hundreds of times faster than that of an electronic computer, and the effect is better. For example, it is used to process the double helix structure photos of filamentous phage taken by electron microscope, which improves the resolution from 0.5 nm to 0.25 nm, thus solving a long-standing debate in biophysics.
Another development of holography is that laser is used as light source, and now white light reflection holography has been developed, and the technology of using sunlight and electro-optic light source has also been invented. This creates favorable conditions for the popularization and wider application of holography.
Holography also has great development potential in optical information processing, integrated optics and medical research.
