)The line of sight, also known as visual axis or sightline (also sight line), is an

).
The term "line" typically presumes that the
refracted by a lens or density changes in the traversed media, or deflected by a gravitational field
. Fields of study feature specific targets, such as vessels in navigation, marker flags or natural features in surveying, celestial objects in astronomy, and so on. To have optimal observational outcome, it is preferable to have a completely unobstructed sightline.
Applications
- Sightline (architecture)
- Line-of-sight range
- Line-of-sight (missile), the straight line between the missile and the target
- Radar horizon
- Line-of-sight propagation, electro-magnetic waves travelling in a straight line
- Line-of-sight fire, shooting directly at a visible target on a relatively flat trajectory
- Line-of-sight velocity, an object's speed straight towards or away from an observer
- Line-of-sight double star, one in which two stars are only coincidentally close together as seen from Earth
- Beyond visual line of sight
