A holographic-moiré technique to obtain separate patterns for components of displacement
- C. Sciammarella, J. Gilbert
- Physics, Engineering
- 1 June 1976
A symmetrical double-beam illumination is used in conjunction with a fictitious fringe system to obtain a moiré pattern which represents the projection of the displacement vector into a single plane.…
Characterization of the panoramic annular lens
- D. Lehner, A. G. Richter, D. R. Matthys, J. Gilbert
- Physics
- 1 December 1996
The panoramic annular lens (PAL) consists of a single piece of glass, with spherical surfaces, that produces a flat annular image of the entire 360-deg surround of the optical axis of the lens. This…
Shadow speckle metrology.

- PhysicsApplied Optics
- 15 January 1986
A computer-based method is developed to measure the out-of-plane motion of a surface which might arise, for example, from the deflection of a structural component or as a result of contouring a 3-D…
Doubly Reinforcing Cementitious Beams with Instrumented Hollow Carbon Fiber Tendons
