Another Step in Ramping up Uncooled Sensors
Multi-megapixel infrared imaging at room temperature for wafer-level scalable FPAs at low-cost
Imaging of gas leaks (especially of methane, but also of other gases) has traditionally been done with portable infrared cameras based on cooled InSb and QWIP FPAs. In these, either the FPA spectral response is tuned to the absorption wavelength of the gas of interest or a spectral filter is used in front of it. Alternatively, high-end spectrally selective (Fourier Transform Infrared – FTIR) cameras (also based on cooled FPAs) are used to detect gas leaks with high sensitivity, but at a price premium.
Now, a new generation of innovative uncooled gas sensors are being developed to not just monitor large gas leaks but also act as monitors for small leaks.
Active Protection Systems (APS) for armored vehicles are becoming a necessity as rocket propelled grenades (RPGs) and anti-armor munitions become more effective against even the best armor. In APS systems an incoming round is detected and tracked and a counter munition is fired to destroy the round before it can damage the vehicle.
In the most recent systems, infrared FPAs are being used.
After numerous delays over a period of ten years, the U.S. Army has finally put 3rd Gen FLIR onto a path where it will become reality. Awards have been made for the Engineering and Manufacturing Development (EMD) for the 3rd Gen B-kit which will be used to upgrade 2nd Gen B-kits in a number of vehicle sighting systems and in targeting systems. The 3rd Gen B-kit consists of a Dewar Cooler Bench (DCB), afocal imager and circuit card assemblies.

The Multiple Kill Vehicle (MKV) program for developing a robust mid-course ballistic missile interceptor is moving to a prototype seeker that will be able to track multiple targets and then guide multiple kill vehicles to destroy them.
The high priority for MRAP (Mine Resistant Ambush Protected) vehicles and their infrared sensors, has led the U.S. Department of Defense to place a DX rating on components, such as uncooled microbolometers that are used in the Driver’s Vision Enhancers (DVE) on these vehicles.
Finmeccanica S.p.A. (Italy) has agreed to acquire DRS Technologies for $5.2 billion in cash.
The U.S. Army’s effort to develop and field a 3rd Gen FLIR is moving into the System Development and Demonstration (SDD) phase.
Manufacturers of uncooled microbolometers are racing to develop and introduce focal plane arrays with 17 micron pixels. The smaller size pixels are seen by producers as a way to differentiate their products and as a path to lower cost and higher volume markets.
Thales UK has been awarded the contract for the UK’s Surveillance System and Range Finding (SSARF) requirement. The company won with the latest version of its Joint-Target Acquisition System (J-TAS), a bi-ocular handheld sight that combines daylight and thermal vision (640 x 480 VOx uncooled microbolometer from DRS) with an eye-safe laser range finder embedded military GPS and azimuth angular referencing.
DRS Sensors & Targeting Systems is seeking to unseat IAI-Tamam as the supplier of the EO/IR system on the U.S. Army’s Shadow 200 Tactical UAV (RQ-7B). The Army wants an upgrade of the Shadow EO/IR system which includes a laser designator.
DRS has been selected for Phase II of the Advanced Soldier Mobility Sensor (ASMS) program - to develop a low power sensor with digitally fused uncooled LWIR and Image Intensified (I2) images for use in a helmet mounted vision sensor for mobility, target detection, and situational awareness in complex terrain.
DRS Technologies is seeking to put an end to its Thermal Weapon Sight woes after having suspended shipments of TWS II for over five months due to a boresighting problem.
The U.S. Army has awarded contracts for the Thermal Weapon Sight II (TWS) Bridge, which is the largest uncooled program to date.
The U.S. Department of Homeland Security’s SBInet sensor network on the Mexican border went into operation along a 28 mile stretch southwest of Tucson. The first section of the “virtual fence” consists of nine 98 foot towers with visible and infrared cameras that send images to a command center and to specially equipped Border Patrol vehicles.
DRS Technologies has split-out its former Nytech unit which was acquired in 2002. The new company, called N2 Imaging Systems, will continue to operate out of its original Irvine, California offices.
L-3 Infrared Products is taking aim at the military driver’s vision enhancement (DVE) market with a new system intended to be used on tactical wheeled vehicles. The Diver’s Vision System (DVS) makes use of the company’s uncooled BST FPAs which are also used in its commercial automotive night vision system.
The plan to replace the current helmet-mounted night vision goggles (NVG) with a digital Enhanced Night Vision Goggles [ENVG(D)] is moving closer to realization. Although numerous technical hurdles must still be surmounted, the U.S. Army has now laid out a schedule for bringing ENVG(D) into production.
The U.S. Army’s effort to keep pushing the performance of uncooled sensor technology is again bearing fruit. All four contractors developing ultra-small pixel uncooled microbolometers have demonstrated 640 x 480 focal plane arrays with 17 µm pixels in thermal weapon sights.
The Department of Homeland Security has awarded the first phase of the Secure Border Initiative (SBInet) contract to a team led by Boeing. The program is intended to help secure both America’s southern and northern borders with a network of sensors.
DRS Technologies is partnering with Intevac to develop a head-mounted digitally fused night vision goggle. The NVG will digitally fuse images from DRS’ uncooled VOx microbolometers with low light level images from Intevac’s EBAPS (Electronically Bombarded Active Pixel Sensor) low-light-level CMOS imager.
DARPA’s Microsystems Technology Office has awarded four 3-year contracts for the development of near room temperature (or “HOT - High Operating Temperature”) mid-wave infrared focal plane arrays. The FPAs are intended for future use in ground-based threat warning systems.
Irvine Sensors has been awarded a contract by Rockwell Collins Optronics for the miniature thermal imagers for the Future Force Warrior (FFW) head-mounted sensor. The Irvine Sensors cameras are based on the company’s tiny CamNoir which makes use of an IC stacking technique (“Neo-Stack) for producing highly compact electronics packages.
Although the U.S. Army’s TWS II program using high performance 25 µm pixel uncooled VOx microbolometers (640 x 480 and 320 x 240) is just getting started, the next-generation, with 17 µm pixels is already getting underway. Under a program funded by PEO Soldier and with the technical monitoring of the Night Vision & Electronic Sensors Directorate, four companies have been selected to develop 640 x 480 microbolometers with 17 µm pixels and deliver two Thermal Weapon Sights and two thermal imaging modules.
The U.S. Army’s effort to develop standard interchangeable imaging modules based on uncooled VOx microbolometers went into Phase II with the awarding of contracts to BAE Systems Infrared Imaging Systems, DRS Infrared Technologies and Raytheon Vision Systems in September 2005. Under Phase II of the Uncooled B-Kit (UBK) program, the emphasis is on 640 x 480 pixel imaging modules.
