4 Photonics Projects Get Defense Funding



http://photonics.com/Article.aspx?AID=56268

WASHINGTON, June 3, 2014 — The U.S. Department of Defense has awarded funding totaling $28.3 million for four photonics graduate research projects under its Multidisciplinary University Research Initiative (MURI).

Brief summaries of the projects follow. For further information on each project, follow the hyperlinks provided.

• $7.5 million for study of photochemical and photophysical processes involving plasmonic nanoparticles. Potential applications include water remediation, sterilization, distillation and electric power generation.

One project group will examine the charge and energy transfer between plasmons and molecules, while another will use spectroscopy to measure the processes in real time. Team members come from the universities of Columbia, Princeton, Rice, Minnesota and Oldenburg, Germany.

• $7.5 million for exploration of plasma-based photonic crystals and metamaterials that operate in the terahertz range. Potential applications include communications, imaging and remote sensing.

Team members come from the universities of Pennsylvania State, Stanford, Tufts, University of California, Los Angeles (UCLA); University of Texas at Austin; and Washington.

• $6.75 million for research into quantum computers. One goal of the new project is to communicate information between electrical quantum states and light using high-frequency mechanical motion as the intermediary. Specifically, the team will exploit the piezoelectric effect in optomechanical devices so as to transfer information between optical, vibrational and electrical quantum states.

The team includes members from the University of Chicago, Cornell, McGill and Yale universities, and the California Institute of Technology.

• $6.5 million to examine configurable metasurfaces that manipulate light for advances in lenses, communications, imaging and quantum information.

Team members come from the universities of Harvard, Columbia, Lund, Purdue, Stanford, Pennsylvania and Southampton.

The photonics projects are among 24 basic research initiatives at 64 academic institutions receiving a total of $167 million over the next five years from DOD. Initially, 361 white papers were received, 88 of which were selected for more detailed proposals.

DOD said past MURI projects have led to advances in laser frequency combs for precision in navigation and targeting, atomic and molecular self-assembly, and spintronics.

Department of Defense awards $23 million dollar grant to use THz in surveillance radar imagery



In one of the largest grants awarded to the university in its history, a University of Massachusetts Lowell lab has received $23 million from the U.S. Army., in part thanks to Mansfield native Prof. Robert Giles.
The grant is for the UMass Submilimeter-Wave Technology Lab. The submilimeter-wave is term used to describe a type of rediation. Microwaves are bigger than, and infrared waves are smaller. The UMass lab primarily researches terahertz-frequency measurement systems, which have many different applications, from medical devices to military radar installations.
 The lab has developed and applied these technologies in the areas of military surveillance, homeland security, medical diagnostics and scientific and academic research.
The grant adds to 2006 funding from the U.S. Department of Defense, which awarded the lab $27 million to fund its research over five years.
“This latest grant is a continuation of our program to assist the government in acquiring and analyzing surveillance radar imagery,” Giles said. “It is a testament to and recognition of our high level of expertise in the field. Our research is focused on using terahertz-frequency sources and receivers to scale the Army’s millimeter-wave and microwave airborne radar systems.”
The research has been going on since 1979. From a military standpoint, the technology and research allowed for radar machines to get a defined and easily recognizable radar "footprint" for any type of aircraft or vehicle.  Such radar fingerprints are useful for quickly identifying whether an incoming object in the battlefield is a friend or foe.
“As a member of the Expert Radar Signature Solutions consortium developed by the National Ground Intelligence Center, we and our government sponsors are the only research program that uses terahertz-frequency measurement systems to collect real-world radar signature data,” Giles said.
On the medical side, they are useful for detecting non-melanoma skin cancer. Terahertz rays are non-ionizing and have no known harmful effects on living tissue. Also, terahertz rays have a shorter wavelength than microwaves, offering perhaps higher resolution for imaging applications.
Cecil Joseph, a post-doctoral researcher at the lab, has demonstrated there is sufficient contrast between healthy and cancerous tissue at terahertz frequencies. This could lead to a simpler and more cost-effective diagnostic tool for treating skin cancer.
“With sufficient external funding, we are hoping to build the hardware required for clinical studies,” Giles said.
In addition to its work for the Army, the research lab has used its unique capabilities to fulfill radar-measurement requests from other Department of Defense agencies as well as defense-related laboratories and companies, including MIT Lincoln Lab, Raytheon, Boeing and Lockheed-Martin.

T-4000 likely candidate for use on the F-35 fighter

There has been comment on this topic before, on this blog, but it's nice to see "official" confirmation.

Panel Step/Gap Mismatch Measurement - Summary for phase 2 funding

Title
Panel Step/Gap Mismatch Measurement
SBIR Topic Number
AF082C-001
Summary Report Type
Phase I Summary
Summation
In the Phase I work, we demonstrated the feasibility of the TD-THz method to measure the dimensions of the ground-plane step and gap through otherwise opaque boots and coatings. We acquired step and gap data on coupons with realistic boots, coatings and substrates to demonstrate the accuracy and precision of the sub-surface TD-THz measurement. We developed a hand-held TD-THz step and gap mismatch measurement system concept to be prototyped in Phase II. This system concept will be able to measure the sub-surface ground-plane step and gap dimensions on all 19 types of seams of panels on the F-35 aircraft. The first application of the measurement system will be in the OEM manufacture of the F-35. Later, the step/gap measurement system can be used in a depot environment to set the step and gap of pre-coated replacement panels, and then eventually by Air Force field service personnel. The TD-THz step/gap mismatch system is based on our T-RayTM 4000 TD-THz instrumentation platform. A hand-held high speed plug-in TD-THz line scanner will acquire a B-scan across a seam and rapidly calculate the step and gap dimensions. The proposed instrument will be able to measure substrate step/gap dimensions through a variety of coating and paints. The TD-THz measurement process is suitable for both composite (conductive and non-conductive) and metallic substrates. TD-THz reflection non destructive evaluation imaging is like an electromagnetic analog to a laminographic ultrasound B-scan, but with several advantages: The TD-THz measurement is non-contact, requires no special preparation of the surface, can be used to determine the dimensions of small structures with precision better than one thousand of an inch.
Anticipated Benefits
Upon successful completion of Phase II, the proposed TD-THz inspection system will provide the Air Force with a highly capable non-destructive, non-contact, single-side inspection method for the determination of subsurface step/gap dimensions on aircraft doors and panels. The Phase II prototype system will be capable of accommodating all configurations required to be measured on the full-scale aircraft, including the various material suites, joint designs, and contours.
