Driving a laser scanning section using a basic period of a pulse signal based on a period of a resonance frequency and accumulated period errors to produce a correction period quantity
摘要：
A laser projector can generate a pulse signal capable of being generated according to the resolution of the clock signal, the pulse signal having a basic period and a basic pulse width each infinitely approximated to the characteristics of the resonance frequency. Moreover, because the laser projector can generate a pulse signal capable of correcting the errors led to be included in the approximated pulse signal, the laser projector can drive the scanning section with a horizontal vibration width corresponding to the resonance frequency, and can suitably display a projected image on a projection plane.
摘要（中）：

激光投影仪可以产生能够根据时钟信号的分辨率产生的脉冲信号，脉冲信号具有基本周期和基本脉冲宽度，每个基本脉冲宽度无限接近谐振频率的特性。 此外，由于激光投影仪能够产生能够校正导致包含在近似脉冲信号中的误差的脉冲信号，所以激光投影仪可以以对应于共振频率的水平振动宽度驱动扫描部，并且可以适当地显示 投影图像在投影平面上。
