Target-electrowetting-liquid-lens shortest response time control method and system

The invention relates to a target-electrowetting-liquid-lens shortest response time control method and system. ArbExpress software is used to draw a driving voltage outer envelope waveform and the waveform is transmitted to a function generator. And the waveform is amplified by a high voltage amplifier so as to generate a high voltage bipolar rectangular driving voltage signal containing an overdrive voltage. The driving voltage signal is applied to an electrowetting liquid lens. A liquid level jitters at the moment when a voltage is applied to the lens. A focal length is changed. A luminous flux changes after continuous lasers pass through the electrowetting liquid lens. An oscilloscope displays a luminous flux change condition captured by a photoelectric detector. The response waveformsof the electrowetting liquid lens driven by different driving voltage waveforms are obtained through a data acquisition and processing module. Through using a driving mode of firstly carrying out overvoltage and then reducing
