Scanning pattern and signal processing for optical coherence tomography

An OCT system for measuring the retina as part of an eye health monitoring and diagnostic system. The OCT system comprises: an OCT interferometer, wherein the interferometer comprises a light source or a measurement beam and a scanner for moving the beam over the retina of a patient's eye; and a processor configured to execute the instructions to cause the scanner to move the measurement beam over the retina in a scan pattern. The scan pattern is a continuous pattern including a plurality of lobes. The measurement beam may be moved over the retina by movement of the mirror, which intercepts the measurement beam and redirects the measurement beam. The mirror position may be varied by applying a drive signal to one or more actuators responsive to the drive signal by rotating the mirror about one or more axes. 一种用于测量视网膜的OCT系统，作为眼睛健康监测和诊断系统的一部分。OCT系统包括：OCT干涉仪，其中干涉仪包括光源或测量光束和用于在患者眼睛的视网膜上移动光束的扫描仪；以及被配置为执行指令以使扫描仪以扫描图案在视网膜上移动测量光束的处理器。扫描图案是包括多个波瓣的连续图案。可以通过反射镜的运动使测量光束在视网膜上移动，反射镜拦截测量光束并使测量光束重定向。可以通过将驱动信号施加到一个或更多个致动器来改变反
