Seeing the World and the Mission Elbit Systems’ Advanced Head-Mounted Display for Pilots and Soldiers

Elbit Systems has filed a patent for an advanced head-mounted image display system designed to overlay mission-critical information on the user’s view of the real world in an augmented reality configuration – while maintaining full situational awareness of their physical surroundings. The system’s optical architecture uses a dual-element design with reflective components and precisely controlled optical power to project sharp, stable images directly to the eye without obscuring the wearer’s view of their environment.

The Problem

Head-mounted display systems for defence, aviation and specialised commercial applications face a fundamental optical challenge: how to project a bright, high-resolution image to the user’s eye while still allowing them to see the world around them clearly. A soldier or pilot who cannot see their environment clearly because their display is interfering with their vision is in danger – but one who must look away from their display to read critical information is also at a disadvantage.

Traditional heads-up display approaches have struggled to achieve the combination of high image quality, wide field of view, compact form factor and optical transparency that demanding operational applications require. Single-element combiner optics limit the designer’s ability to correct for aberrations and control the optical path. The result is a difficult trade-off between image quality and see-through performance that many existing systems fail to resolve satisfactorily.

More complex multi-element optical designs can in principle achieve better performance, but adding optical elements adds weight, bulk and alignment complexity – all significant problems in a head-mounted system worn in demanding physical environments.

What This Invention Does

Elbit’s head-mounted display system uses two optical elements in sequence, each with a receiving surface, a reflective element and a projecting surface. At least one surface in each element possesses optical power – meaning it can focus, redirect or otherwise process the light passing through it. This dual-element architecture gives the optical designer substantially more degrees of freedom to control the image quality and optical path than a single-element combiner allows.

An image source projects one or more light beams representing the images to be displayed. The beams pass through the first optical element, then the second, and are finally combined with the wearer’s view of the real world through an at least partially reflective element. This combiner element enables the user to see both the displayed images and the real world simultaneously – the fundamental requirement of any augmented reality or heads-up display system. The arrangement is designed so that both the real world view and the virtual image appear clear and sharp to the wearer.

Key Features

Dual optical element architecture. Two sequential optical elements – each with receiving, reflective and projecting surfaces – provide greater aberration correction and optical path control than single-combiner designs, enabling higher image quality in a compact form factor.

Optical power at multiple surfaces. By distributing optical power across multiple surfaces within the two elements, the design achieves the focusing and correction requirements of the system without relying on large, heavy optical components.

See-through capability. The at least partially reflective final combiner element allows the wearer to see their real-world environment while simultaneously viewing the displayed image – maintaining full situational awareness throughout.

Head-mounted form factor. The system is designed for head-mounting, prioritising compactness and weight management while achieving the optical performance demanded by defence and aviation applications.

Multiple image support. The image source is capable of projecting one or more light beams associated with one or more respective images, enabling the display of complex, multi-layer information overlays such as targeting data, navigation and sensor feeds.

Who Is Behind It?

ELBIT SYSTEMS LTD. is one of Israel‘s largest defence technology companies, with a global presence in avionics, unmanned systems, land systems and intelligence. Elbit is known internationally for its airborne helmet-mounted display systems, including the widely deployed Joint Helmet Mounted Cueing System (JHMCS). The inventors are Shimon Aburmad, Adi Charny, Yotam Gil, Liad Ben Ishai and Yaniv Toledano. This application is a divisional of AU 2024322877. The application is managed by James & Wells Intellectual Property in Canberra.

Why It Matters

Head-mounted display technology is one of the most consequential areas of applied optics in both defence and civilian contexts. For pilots, helmet-mounted displays that project targeting, navigation and aircraft status information directly to the eye – while maintaining a clear view of the outside world – provide a decisive tactical advantage and safety benefit. For ground forces, compact augmented reality systems can transform how soldiers navigate, communicate and operate in complex environments.

Beyond defence, the optical principles behind high-performance head-mounted displays are directly relevant to the growing market for augmented and mixed reality devices in industrial, medical and consumer applications. Elbit’s optical expertise – developed over decades in demanding military contexts – positions the company as a significant contributor to the broader advancement of wearable display technology. With IPC classifications covering reflective optics (G02B 17/08) and head-mounted displays (G02B 27/01), the patent sits at the core of modern optical engineering for wearable systems.

Related Concepts

Head-mounted displays for defence and aviation must achieve a difficult combination: projecting sharp, bright imagery to the eye while preserving full transparency to the outside world. Augmented reality optics designed for demanding military environments – where weight, bulk, and reliability are critical – represent some of the most advanced applied optics in the world. Advances by companies like Elbit Systems are increasingly crossing over into industrial and consumer mixed reality applications.
