Raytheon has demonstrated a new type of infrared camera that ditches the conventional approach of capturing full video frames, instead recording only the pixels that change from one instant to the next. The result, according to RTX, is a sensor that can lock onto fast-moving aerial threats without the motion blur that plagues traditional infrared trackers.
The demonstration, conducted under the U.S. Department of Defense’s Fast Event-based Neuromorphic Camera and Electronics (FENCE) program, marks what Raytheon describes as a first-of-its-kind achievement: an event-based camera operating in the mid-wave infrared band, the spectral range between roughly three and five micrometers where rocket exhaust, jet engines, and warm airframes stand out sharply against cooler backgrounds. RTX announced the demonstration in spring 2026, though the company did not disclose the exact date or location of the test.
For air defense operators watching for hypersonic missiles or fast-maneuvering drones, the technology addresses a specific and growing problem. Targets are getting faster than the sensors designed to find them.
How the sensor works
Traditional infrared cameras scan every pixel at a fixed frame rate, producing massive data streams regardless of whether anything in the scene has moved. That brute-force approach works well enough for slower targets, but it creates processing bottlenecks and motion blur when objects cross the field of view at extreme speed.
Raytheon’s event-based sensor takes a fundamentally different approach, one borrowed from neuromorphic engineering, a field that designs hardware to mimic how biological nervous systems process information. Each pixel in the camera fires independently the moment it detects a brightness change. Pixels viewing static background stay silent. The sensor’s output is a sparse, high-speed stream of data concentrated entirely on whatever is moving.
That architecture offers two practical advantages. First, the data volume drops dramatically, which means onboard processors can work faster with less computational strain. Second, because individual pixels respond at the microsecond level rather than waiting for the next full frame, the sensor can track objects that would blur or disappear entirely on a conventional infrared camera running at standard video rates.
During the demonstration, Raytheon showed the FENCE camera maintaining a lock on high-speed objects without the degradation typical of full-frame infrared imagery, according to RTX.
Why mid-wave infrared matters
Event-based vision sensors are not entirely new. Companies like Prophesee and iniVation have sold neuromorphic cameras for industrial inspection and autonomous vehicles for years. But those commercial systems operate in the visible or near-infrared spectrum, wavelengths useful for factory floors and highway driving but insufficient for military threat detection at long range.
The mid-wave infrared band is the workhorse of missile warning and air defense because it captures thermal signatures that visible-light cameras cannot see. Extending neuromorphic event-based architecture into that band required Raytheon to work with different detector materials, cryogenic cooling systems, and noise profiles than anything the commercial neuromorphic sector has tackled. That crossover from visible-spectrum lab work to defense-grade infrared hardware is the specific technical milestone Raytheon is claiming.
What the Pentagon has not said
As of May 2026, several important details remain undisclosed. The DoD has not released performance metrics from the FENCE demonstration, so independent observers cannot evaluate tracking speed, detection range, or false-alarm rates. Without those numbers, comparing the camera’s real-world capability to existing infrared search-and-track systems already fielded on Navy destroyers and Air Force fighters is not possible.
Funding levels, contract timelines, and integration plans for FENCE have not appeared in publicly available budget documents or acquisition announcements. It is unclear which military branch would field the sensor first, whether it is intended as a standalone tracker or a component inside a larger weapon system, and whether the program has advanced beyond prototype status toward a formal program of record.
Integration poses its own set of questions. A neuromorphic sensor’s output looks nothing like conventional video. Feeding that data into existing fire-control systems, command-and-control networks, and operator displays would require software adaptation across multiple layers of the kill chain. Raytheon has not publicly detailed how far that work has progressed.
Where this fits in the broader defense picture
The FENCE demonstration arrives as the Pentagon is investing heavily in sensor modernization to counter hypersonic weapons. Hypersonic glide vehicles, which travel above Mach 5 and can maneuver unpredictably during flight, have driven urgent demand for tracking systems that can keep pace with targets conventional radars and infrared sensors were never designed to follow. The Missile Defense Agency, the Space Development Agency’s satellite-based tracking layer, and multiple classified programs are all pursuing faster, more responsive sensor architectures.
Raytheon’s event-based camera represents one approach to that problem, built around the idea that processing less data more intelligently beats processing more data at brute force. Whether the FENCE sensor can deliver on that promise at operational scale is a question the public record cannot yet answer.
How to weigh Raytheon’s claims without independent testing
RTX’s announcement functions as a corporate disclosure, and defense contractors routinely publicize successful demonstrations to signal capability to the Pentagon, Congress, and allied governments considering procurement. That framing does not make the claims false, but it means the performance descriptions reflect the manufacturer’s account rather than independently verified benchmarks. The original article cited a DoD Chief Information Officer webpage as a reference for the FENCE program name, but that link leads to a generic accessibility statement rather than a program-specific page, making it a weak corroboration. The FENCE acronym and its DoD connection are traceable through RTX’s own materials, yet no standalone Pentagon document publicly confirming the program’s scope or status has surfaced as of May 2026. Until third-party testing or a Government Accountability Office review appears, the FENCE camera’s real-world edge over existing infrared trackers remains Raytheon’s word.
