Optical encryption using a liquid phase mask

Analysis of natural frequency for imaging interface in liquid lens

“…Since electrowetting liquid lens was innovated, it has been received increased attention across a number of scientific inquiries in recent years, [1][2][3][4][5][6][7][8][9][10][11][12] such as the imaging of portable lens, [4,5] realizing the bionic compound eyes, [6] composing array displays, [7] enhancement of scanning microscopes, [8,9] and construction of holographic display systems. [10] There were also interesting studies of the liquid-liquid (L-L) interface in the lens for interference imaging, [11] which can be used to enhance the encryption randomness of phase mask in optical communication systems to prevent confrontational attacks.…”

“…[10] There were also interesting studies of the liquid-liquid (L-L) interface in the lens for interference imaging, [11] which can be used to enhance the encryption randomness of phase mask in optical communication systems to prevent confrontational attacks. [12] In all kinds of applications, the rapid response of milliseconds is a major advantage for the liquid lens. [13] The response time mainly depends on the time difference between the applying of voltage signal and the stabilization of the L-L interface.…”
