Extending Field of View in Advanced Imaging Systems
New program focuses on developing curved infrared focal plane arrays to improve optical performance and widen field of view while reducing system size of military imagers
The military relies on advanced imaging systems for a number of critical capabilities and applications – from Intelligence, Surveillance, and Reconnaissance (ISR) and situational awareness to weapon sights. These powerful systems enable defense users to capture and analyze visual data, providing key insights both on and off the battlefield. Today, nearly all imaging systems rely on detector arrays fabricated using planar processes developed for electronic integrated circuits on flat silicon. While significant progress has been made in advancing these technologies for narrow field of view (FOV) systems, optical aberrations can limit the performance at the periphery in wide FOV systems that then require large, costly, and complex optics to correct. The trade-off for correcting optical aberrations by using large, heavy lenses is a reduction in optical signal and a large size penalty, which limits their use for new and emerging capabilities.
“Tremendous progress has been made over the past 20 years towards making multi-megapixel infrared (IR) focal plane arrays (FPA) for imaging systems cost effective and available to the Department of Defense,” said Dr. Whitney Mason, a program manager in DARPA's Microsystems Technology Office (MTO). “However, limitations to the technology's performance and size remain. Current advances on the commercial side have shown the viability of small area, curved FPAs (CFPAs) for visible cameras. While these technologies have shown modest benefits, more must be done to achieve the performance and size requirements needed for imaging systems used in emerging defense applications.”
DARPA developed the FOcal arrays for Curved Infrared Imagers (FOCII) program to expand upon the current commercial trend for visible sensor arrays by extending the capability to both large and medium format midwave (MWIR) and/or longwave (LWIR) infrared detectors. The program seeks to develop and demonstrate technologies for curving existing state-of-the-art large format, high performance IR FPAs to a small radius of curvature (ROC) to maximize performance, as well as curve smaller format FPAs to an extreme ROC to enable the smallest form factors possible while maintaining exquisite performance.
FOCII will address this challenge through two approaches to fabricating a curved FPA. The first involves curving existing state-of-the-art FPAs, while keeping the underlying design intact. The focus of the research will be on achieving significant performance improvements over existing, flat FPAs, with a target radius of curvature of 70mm. The fundamental challenge researchers will work to address within this approach is to mitigate the mechanical strain created by curving the FPGA, particularly in silicon, which is very brittle.
The second approach will focus on achieving an extreme ROC of 12.5 mm to enable a transformative reduction in the size and weight compared to current imagers. Unlike the first approach, researchers will explore possible modifications to the underlying design, including physical modifications to the silicon that could relieve or eliminate stress on the material and allow for creating the desired curvature in a smaller sized FPA. This approach will also require new methods to counter the effects of any modifications during image reconstruction in the underlying read-out integrated circuit (ROIC) algorithm.
The FOCII program is hosting a proposers' day on August 13, 2019 at the Executive Conference Center, 4075 Wilson Blvd., Suite 300, Arlington, Virginia, 22203 from 9:00 a.m. to 4:00 p.m. EDT. The purpose of this meeting is to provide information on the FOCII program, promote additional discussion on this topic, address questions from potential proposers, and provide an opportunity for potential proposers to share their capabilities and ideas for teaming arrangements.

£85M contract to boost Type-23 capabilities
The Ministry of Defence has signed an £85 million contract with Rolls-Royce to maintain the engines of the Royal Navy's Type-23 frigate fleet. The contract includes a comprehensive support package to Spey gas turbines, including the overhaul of engines, provision of spares, as well as engineering and safety support. Updates to the turbines are vital as they boost propulsion in the Type-23 Frigates. They are also key pieces of equipment for Anti-Submarine Warfare. The world-beating Type-23 frigate is able to carry out a wide variety of operations, from securing the UK's vital maritime trade routes East of the Suez Canal to safeguarding British interests in the South Atlantic. Defence Minister Stuart Andrew announced the contract at HMNB Devonport where he saw Thursday War training which prepares the Royal Navy for war-fighting, humanitarian relief and emergency situations through a variety of drills and exercises. Defence Minister Stuart Andrew said: This £85m contract demonstrates the UK's commitment to modernisation through the maintenance of our formidable Type-23s. This work continues the British tradition of supporting our closest allies and solidifying our global position as world-leaders in advanced maritime technology and development. The contract will see Rolls-Royce overhaul thirty Type-23 engines from the UK and NATO partners Belgium, Portugal and the Netherlands. The contract is expected to deliver a £35 million increase in savings to the MOD over the next eight years, by incentivising Rolls-Royce to improve repair schemes, minimise unnecessary work and procure spares at a lower cost. This will result in shorter, less expensive overhauls. Rolls-Royce will project manage the support contract, while the main overhaul and repair work will be carried out by RWG based in Aberdeen, supporting up to 25 UK jobs across both companies. Scotland benefits from MOD expenditure of £300 per person each year and a huge investment in local industry and commerce of £1.6 billion. UK Defence also supports over 10,000 industry jobs in Scotland and the nation is renowned for building the world's finest warships including the UK's new aircraft carriers and the Royal Navy's state-of-the-art Type-26 frigates. Defence Equipment and Support Chief of Materiel Ships Vice Admiral Chris Gardner said: The Type 23 frigate is central to Royal Navy operations around the world and keeping it at the forefront of operations is critical. This contract will ensure Rolls-Royce continues to innovate through improving repair schemes, minimising unnecessary work and procuring spares cheaper. This will result in shorter, less expensive overhauls, which is good news for the Royal Navy and good news for the tax payer. Matt Nadin, Director Naval Fleet Services at Rolls-Royce said: This vital support contract builds upon our Rolls-Royce target to achieve and sustain increased Spey engine availability to the Royal Navy and their NATO partners, The Netherlands, Belgium and Portugal. This contract highlights our successful collaboration with the UK Ministry of Defence to provide the technical support and repair activities required to not only keep these engines in-service with the Royal Navy and their NATO partners, but also to deliver increased value for money. https://www.gov.uk/government/news/85m-contract-to-boost-type-23-capabilities
