A variable focus lens system can include a variable focus lens, one or more electrodes, a signal generator configured to supply voltage to the one or more electrodes to vary the focal length of the variable focus lens, and a controller configured to apply a voltage to the one or more electrodes and receive information indicative of a capacitance that results from the applied voltage. The controller can be configured to determine a temperature of the variable focus lens based at least in part on the capacitance or applied voltage. The variable focus lens system can include a temperature sensor, and the controller can be configured to receive temperature information from the temperature sensor and calibrate the temperature sensor based at least in part on the received temperature information, the applied voltage, and the received capacitance information. 一种可变焦透镜系统可包括可变焦透镜；一个或多个电极；信号发生器，信号发生器被配置为向该一个或多个电极提供电压以改变可变焦透镜的焦距；以及控制器，控制器被配置为向一个或多个电极施加电压并且接收指示所施加的电压产生的电容的信息。控制器可被配置为至少部分地基于电容或施加的电压来确定可变焦透镜的温度。可变焦透镜系统可包括温度
