This paper proposes a phase modulation method for Lissajous scanning systems, which provides adaptive scan pattern design without changing the frame rate or the field of view. Based on a rigorous analysis of Lissajous scanning, phase modulation constrains and a method for pixel calculation are derived. An accurate and simple metric for resolution calculation is proposed based on the area spanned by neighboring pixels and used for scan pattern optimization also considering the scanner dynamics. The methods are implemented using MEMS mirrors for verification of the adaptive pattern shaping, where a 5-fold resolution improvement in a defined region of interest is demonstrated.
本文提出了一种用于李萨如扫描系统的相位调制方法，该方法可在不改变帧率或视场的情况下实现自适应扫描模式设计。基于对李萨如扫描的严格分析，推导了相位调制约束条件和像素计算方法。基于相邻像素所跨越的面积，提出了一种精确且简单的分辨率计算指标，并将其用于扫描模式优化，同时还考虑了扫描仪的动态特性。这些方法通过微机电系统（MEMS）镜来实现，以验证自适应模式整形，其中在定义的感兴趣区域内分辨率提高了5倍。
