CN107646192B 用于激励功率减小的使用动态相位偏移的扫描激光投影仪、谐振系统和方法 有权

用于激励功率减小的使用动态相位偏移的扫描激光投影仪、谐振系统和方法
Abstract:
一种用于谐振系统的驱动电路(170)提供具有振幅(513)和相位的激励信号(173)。所述谐振系统提供代表振荡振幅的反馈信号(175)。激励信号的振幅通过修改激励信号相位而降低，以获得实质上恒定的反馈信号振幅。
Abstract(English):

A drive circuit for a resonant system provides an excitation signal having an amplitude and a phase. The resonant system provides a feedback signal representing an oscillation amplitude. The amplitude of the excitation signal is reduced for a substantially constant feedback signal amplitude by modifying the excitation signal phase.
