The invention protects a anti-peeping display method based on wavefront distortion compensation. The front of the display is covered with an adjustable phase plate array, and the screen light can pass through the phase plate array and generate wavefront distortion. Whether the screen data is exclusively for users or peeping None of them can read the normal information displayed on the screen; the screen data is exclusively for the user to wear wavefront distortion compensation glasses, compensate the screen light wavefront distortion generated by the phase plate and see the screen clearly; the phase distribution and wave length of the phase plate array can be tuned The phase distribution of the front distortion compensation glasses is always complementary, and the two parties are synchronized and consistent through the shared key exchanged by wireless communication; the spy cannot know the content of the key, and even with the wavefront distortion compensation capability, they cannot read the screen information in real time. The invention effectively combines technologies such as wireless communication, key distribution, and adaptive optics to effectively prevent non-cooperative personnel from spying on security-related information displayed on the screen, and provides a new solution for preventing visual hackers in a mobile office environment.
Description
technical field [0001] The invention belongs to the interdisciplinary field of optoelectronics, display optics, adaptive optics and wireless communication, and specifically refers to a method of covering the front of a display with a phase plate to blur the screen, using wavefront distortion compensation glasses to restore screen information, and controlling The phase distribution of the phase plate and the wavefront distortion compensation glasses is synchronized in real time to realize the anti-peep display technology that only the screen data is exclusively for the user to see the screen clearly, especially relates to an anti-peep display method based on wavefront distortion compensation. Background technique [0002] The display of mobile phones and computers is an important medium for information processing platforms to realize human-computer interaction, and it is also the starting point for visual hackers to steal security-concerned information. In mobile office scena...
