A head-up display, or heads-up display, also known as a HUD (/hʌd/) or Head-up Guidance System (HGS), is any transparent display that presents data without requiring users to look away from their usual viewpoints.
The origin of the name stems from a pilot being able to view information with the head positioned “up” andlooking forward, instead of angled down looking at lower instruments.
A HUD also has the advantage that the pilot’s eyes do not need to refocus to view the outside after looking at the optically nearer instruments.
Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles, and other (mostly professional) applications.
Head-up displays were a precursor technology to augmented reality (AR), incorporating a subset of the features needed for the full AR experience, but lacking the necessary registration and tracking between the virtual content and the user’s real-world environment.
The projection unit in a typical HUD is an optical collimator setup: a convex lens or concave mirror with a cathode-ray tube, light emitting diode display, or liquid crystal display at its focus.
This setup produces an image where the light is collimated, i.e. the focal point is perceived to be at infinity.
The Global Aviation Head-Up Display Camera market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Mercury HUD1080 Head-Up Display – Display flight-critical information in high-definition.
The HUD1080 is a digital display designed for modern aircraft. Traditional analog HUDs use expensive, bulky, and obsolete cathode ray tube (CRT) technology that does not support next generation aircraft capabilities.
The HUD1080 features digital light engine technology and a non-obstructive design enabling pilots to see real-time flight images in 1080p without taking their eyes off the action outside.
HUD1080 features a large eye-motion box with more than 24 degrees field of view to eliminate blind spots and reduce eye strain.
The front-end takes as little as 2 inches of vertical space below the glass, allowing large displays to be integrated higher in the cockpit so pilots can keep their heads up during flight.
An unobstructed video camera captures live footage with symbology for training and debriefing purposes.
