PROGRAM INTEREST POC Dr. Wallace Smith, ONR 332 (703)696-0284. The Materials Division of the Office of Naval Research announces a program interest in the area of Materials and Processes for Undersea Ultrasonic Imaging Transducers. This research and development thrust on transducer materials/devices targets systems/applications in three areas: (1) diver-held imaging sonar for Explosive Ordnance Disposal and Naval Special Warfare requirements; (2) UUV mounted imaging sonar for detection, classification and identification tasks in mine countermeasures; and (3) torpedo guidance imaging sonar for shallow water environments. While this program concentrates on transducer materials and device issues, the program will be defined in conjunction with systems applications specialists from the three technical areas noted, in order to insure the rapid application of technology innovations in Navy systems. Innovative materials and device research that holds the promise of substantial improvements in undersea ultrasonic imaging transducers should be summerized in a three to five page concept paper that describes the transducer science research and technology development proposed, as well as its expected impact in the three target applications arenas. Along with a rough order of magnitude of the proposed program's costs, these concept papers should be submitted to: Dr. Wallace Arden Smith, Office of Naval Research, Materials Division, ONR 332, 800 North Quincy Street, Arlington, VA 22217-5660, phone: (703) 696-0284. Fax: (703)696-0934, email: smithw@onrhq.onr.navy.mil. Responses to these initial inquiries will be made on a continuous basis and projects will similarly begin continuously as meritorious research and development efforts are delineated.
