Eye motion artifacts in AO-OCT volume. (top left) A volume consists of a set number of fast B-scans spaced along the $y$ axis with each fast B-scan consisting of a set number of A-lines spaced along the $x$ axis. (top right) The slow B-scan projection image is the projection of the volume onto the $yz$ plane by averaging all pixels along the $x$ axis. The wavy looking pattern is due to axial motion. (bottom) Similarly, the en face projection image is the projection of the volume onto the $xy$ plane by averaging all pixels along the $z$ axis. The abrupt distortion is due to a microsaccade. The irregular spacing is due to tremor motion.
