visual horizon การใช้

• Flying over water at night in the haze, he had no visual horizon.
• Microwaves propagate entirely by point-to-point terrestrial communications links limited by the visual horizon ( about 40 miles ).
• Yet such affinities are more correctly seen as evidence of the first world's expanded visual horizons in this century.
• Line-of-sight transmission on the surface of the Earth is limited to the distance to the visual horizon, about 40 miles.
• Some pilots flying similar routes as Kennedy on the night of the accident reported no visual horizon over water because of haze.
• Classes such as " Iowa " and " South Dakota " could lob shells over visual horizon, in darkness, through smoke or weather.
• Normally, signals in the microwave frequency range travel in straight lines, and so are limited to " visual horizon to around 30 40 miles.
• One GeoVector augmented reality design used compass equipped binoculars along with GPS to superimpose nautical maps on the visual horizon thus improving the safety of navigation.
• Both the NC-1 and the NC-3 were forced to land on the open Atlantic Ocean because the poor visibility and loss of a visual horizon made flying extremely dangerous.
• Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves can line of sight, so their propagation distances are limited to the visual horizon.
• In terms of visual appearance, observers who fall into the hole perceive the black region constituting the horizon as lying at some apparent distance below them, and never experience crossing this visual horizon.
• The observer manipulates the index arm so the reflected image of the body in the horizon glass is just resting on the visual horizon, seen through the clear side of the horizon glass.
• Through multi-stage biting, " ?Bordeaux " drives the viewer from the dark and rich boat and boathouse in the foreground through the harbor to the distant town in a near infinite visual horizon.
• There has been some speculation that JFK Jr ., was attempting to turn the plane, and having lost his visual horizon in the haze and darkness, overbanked the plane and put it into a spin.
• The " Green Checkers " came aboard with two SH-2 helicopters which were used early on in SSSC missions  flying beyond the visual horizon of this warship to visually observe all radar contacts on the surface.
• Physicists generally looked on radio waves as an invisible form of light, a short range phenomenon which could only travel along a line of sight path, and thus its range was limited to the visual horizon like existing forms of visual signaling, making it unsuitable for long distance communication.
• Still, the weather was favorable, and Kennedy had flown into the Vineyard dozens of times, including at least five times at night with no instructor aboard, according to the NTSB . There is every reason to think the flight would have been uneventful had not haze obliterated the visual horizon.
• :: Looking at the Horizon page, it mentions " that the actual visual horizon is slightly farther away than the calculated visual horizon, due to the atmospheric refraction of light rays . " Therefore, at an average eye-level height of 1.70m, you could possibly see as much as the top 32m of the towers.

• 2010  "'Robotic Visual Horizon "' An automated system that allows unmanned aeroplanes to perform complex manoeuvres was adapted from the way a bee's brain processes visual information during flight by researchers and engineers at the Vision Centre, the Queensland Brain Institute and the School of Information Technology and Electrical Engineering at the University of Queensland.
