Abstract

The dynamic response of a double-liquid lens driven by sinusoidal signals with different frequencies and amplitudes is researched experimentally. The results show that the oscillation frequency of the liquid lens interface is twice that of the driving signal at a certain oscillation position. When the driving voltage amplitude is unchanged, and the oscillating position of the liquid interface is stable, the oscillation amplitude increases first and then decreases with the increase of frequency. When the driving voltage frequency is constant, with the increase of the driving voltage amplitude, the deviation of the oscillation position of the liquid interface from the initial position and oscillation amplitude increases. According to the force analysis of the liquid interface, the reasonable explanation of the above experimental results is presented.
