The function of active eye tracking. Tracking: (a) Single frame with vessel and nerve fiber, (b) 10-frame average, (c) 100-frame average. Non-tracking: (d) 100-frame average. Short-term (<1 s) and long-term (several seconds) rms tracking/registration errors are subject-dependent and span the range of ~5 to 15 μm and without tracking from ~50 to >300 μm. Eye tracking can significantly improve stable overlap and efficiency of sequential AOSLO image capture by limiting the magnitude of eye movement excursions
