DR. EDWARD A. INGHAM – Consultant

General Background/Experience
After retiring from the US Air Force, Dr. Ingham worked for two years as a defense contractor with Research Associates of Syracuse and is currently a Boeing 767 First Officer with Federal Express.

2004-2006 – Research Associates of Syracuse
At RAS, Dr Ingham was contracted to the Air Force Research Laboratory, Rome New York, as a technical advisor in the Measurements and Signatures Intelligence branch. Specific subject areas included: advanced synthetic aperture radar imaging, LASER processing and exploitation, high power microwave weapons exploitation, concealed weapons detection, and through the wall radar sensing. He also worked directly with RAS on the Horizontal Fusion Initiative in an effort to maximize tactical aircraft effectiveness in the modern battlefield.

1984-2004 – US Air Force
Dr. Ingham completed his career by commanding the USAF Aggressors; an elite squadron dedicated to assuring readiness for US and Allied combat air forces. He supervised over 25 pilots, air weapons directors, and ground personnel specially trained to replicate air and ground threat operations and assess US and Allied performance. As an Aggressor, he coordinated and led all adversary air and ground threats during Red and Maple Flag exercises involving training missions with over 80 combat aircraft. Additionally, his unit was identified by the Air Force Chief of Staff as the dedicated adversary air for F/A-22 testing, validation, and initial cadre pilot training.

Dr. Ingham also served as the Director of Operations for Red Flag. He was directly responsible for maximizing the training opportunities and safe conduct of Red Flag missions routinely conducted twice a day over a two-week period. Each Red Flag mission required detailed coordination with the Nellis Combined Air and Space Operations Center, the Nevada Test and Training Range, the Nellis Air Combat Training System, and Nellis AFB airfield support facilities.

In 2000, Dr. Ingham was the Operations Officer of the 310th Fighter Squadron, the USAF’s primary Night Systems and Forward Air Control F-16 training squadron. He supervised over 30 Low Altitude Navigation and Targeting Infrared for Night, Forward Air Control, and Night Vision Goggle F-16 Instructor Pilots.

In 1998, Dr. Ingham was an action officer for the Barry M Goldwater Range in Southern Arizona. He was instrumental in integrating an FAA operated Air Route Surveillance Radar with military operations and acquiring electromagnetic and infrared threat replication systems for advanced combat training.

BOB CLEMENT – Eastern Regional Manager

ATT is pleased to announce that Bob Clement has joined the company as Sales & Marketing/Photogrammetry Specialist as of October 2006. Bob’s primary role will be to market equipment leasing and contract inspection services and to develop the market and processes for ATT’s newly acquired photogrammetry systems. He will also be involved in the development of strategic partnerships with various software and hardware metrology companies. Bob’s overall focus will not only be to grow ATT’s photogrammetry business, but also to expand ATT’s overall presence in the metrology service providers’ marketplace.

Bob will be based in Greenville, South Carolina, which will provide ATT a much wider base from which to meet our customers’ needs.

Bob has been involved in automotive metrology with BMW for the past 12 years. He has been involved in the production launch of every US built BMW to date. In his job, he pioneered the introduction of photogrammetry to the automotive world, which has led to new applications and software capabilities. His success with new technologies led to BMW relying on his knowledge and abilities as an “out of the box” thinker to come up with reliable technologies to solve complicated metrology problems. Bob also has been a strong and committed supporter of the Coordinate Metrology Systems Conference and can be largely credited for his leadership contributions to the current success of the organization.

ATT feels strongly that Bob’s experience and successful track record will prove very useful to ATT’s customers. If you would like to contact Bob, either to discuss measurement issues, or to inquire about a specific project, he can be reached through one of the following methods: (425) 867-5356 or bobc@attinc.com.

What is 3D Metrology?

3D Metrology is the art and science of creating extremely accurate three dimensional data models of complex surfaces and objects. 3D metrology has become more and more important with the rapid growth of the extensive computer modeling that is at the heart of today’s technological advances. 3D Metrology takes us from existing objects to the theoretical model, and from the theoretical model to new accurately manufactured objects. 3D Metrology is the key connection between the physical and virtual worlds.

What is a Computer Aided Theodolite?

A theodolite is an optical instrument that can be manually aimed at a target and a horizontal and vertical angle recorded. A computer aided theodolite system is one where up to 8 theodolites can be connected to a computer to record angular readings from each of the theodolites and compute x, y, z coordinates for points of interest. The angular readings are accurate to +/- 1/2 of an arcsecond. An arcsecond is 1/3600 of a degree.

What is a Laser Tracker?

A laser tracker is similar to a theodolite, in that it records horizontal and vertical angles, but has the added feature of being able to record a distance using an interferometer at the same time. This permits the calculation of x, y, z values for any point from one tracker position (theodolites require a minimum of 2 positions). The angular readings are in the +/- 1/2 arc second range, and the distance is recorded by an interferometer to +/- 2 ppm.

What is a Portable CMM/Arm?

A portable CMM Arm is used to inspect, reverse engineer, or perform CAD-to-Part Analysis on parts, fixtures and assemblies with remarkable accuracy.Measures within +/- .0010 inches (+/- .25 mm). Available in spherical ranges of 4 ft – 12 ft (1.2m to 3.7m).

Basic Computations

With theodolites, the basic calculation is to use two horizontal and vertical angles and a baseline distance established between the theodolites to “triangulate” the position of the intersection of the two lines of sight to the point.

More complex computations are used for defining the location of the theodolites relative to a defined reference system through “a least-squares coordinate transformation”. This process essentially allows moving a set of points and overlaying them on a similar set of points in a desired reference system by minimizing the sum of the squared deviations.

Laser trackers, since they don’t require multiple instruments to read a single point to generate its coordinate values, primarily use the coordinate transformation to relate different sets of point measurements to a common reference frame. This would include relating points measured from different tracker set-ups.

Benefits of using CAT, or Laser Tracker, or Portable CMM/Arm

Fast Data Collection – reduces downtime of objects being measured.
Highly Accurate – greater accuracy than conventional methods of using jig transits, levels, scales.
Highly Portable – equipment can be easily shipped by air to a customer site or rolled across the factory.
Surface Scanning – Laser trackers can collect data at a veryrate of 1000 points/second.
