The z-axis then points along the line of sight, and so measures distance away from the eye.
Each line of sight samples an azimuthal section of the outer shell as shown.
One potential problem - possible confusion from background stars, particularly eclipsing binaries near the line of sight to a foreground target star - is addressed here.
Thus, the robot moves in lines that are parallel to the initial line of sight.
The standard patch was in the center of the scene and moved from trial to trial along the observer's line of sight in depth.
The line of sight was 10m above the equatorial plane.
The intensity of light incident on a test surface placed along the line of sight through the doorway varied with depth.
The rotational pattern depicted a smooth rotation around the gaze axis or line of sight centered at the middle of the monitor.
