53.2: Invited Paper: Evaluation of Optical Performance and Image Quality for Aviation Head‐up Displays (HUDs) Applied Under High Ambient Light.

The HUD (Head‐Up Display) is an optical display system that is commonly used in aircraft as a flight aid to project aircraft flight information onto the display screen (often a type of transparent flat lens) directly in front of the pilot's field of view. This allows the pilot to maintain a level view while taking into account instrument parameters and external visual references in the same field of view. HUDs allow pilots to see crucial navigation, flying, and energy management data on a screen at eye level without having to glance down at their instruments or take their eyes off the outside world. It has been demonstrated that HUDs lessen the pilot workload, improve situational awareness, and decrease accidents. Thus, it is crucial to characterize optical performance and image quality accurately and precisely for aircraft HUDs. In this paper, we reviewed the parameters of optical performance and image quality for aviation‐type HUDs applied under high ambient light levels. [ABSTRACT FROM AUTHOR]
