8. New Technology Roots

Publication Date



My purpose in this talk is to introduce the Poster Session that follows. We believe that most of the work presented in that session is ready for the next step of development. One of the key elements in this step is to find the "window" which can make use of these ·new pieces of technology. I truly appreciate the opportunity to hear the talks from the Air Force, Navy, and the Army which will help to identify some of these slots. I'd like to give a bit of our program philosophy that is important in this regard. On Wednesday, you heard so.e of the fundamentals of the ultrasonic work that we have been doing; work that has resulted in procedures which now are capable of producing .numbers that characterize a defect. In achieving this capability, there are a number of improvements in various elements of the ultrasonic apparatus that have a .useful identity of their own, i.e., they have a spinoff capability. Those are the elements that we wish to talk about this morning and to identify as having reached a proof-of-principle plateau, and, if you will, are ready now for the next question. In the context of Dr. Frank Kelley's remarks and the needs identified by the Tri-Services, we must now seek to put them into specific problems for evaluation. As indicated also by Dr. Kelley, this is a very important step in developing a technology flow within the DoD. However, research must continue in order that future results may also be harvested. With this background in mind, I'd like to introduce some of the topics that you'll see in the Poster Session that have been developed under ARPA/AFML sponsorship.
