The goal of this research was to utilize statistical methods to evaluate the probability of detection (POD) of defects in coatings using electronic shearography. The coating system utilized in the POD studies was to be the paint system currently utilized on the external casings of the NASA Space Transportation System (STS) Revised Solid Rocket.
Shearography Technology and Applications: A Review Article (PDF Available) in Measurement Science and Technology 21(10) August. Non-destructive Testing and Damage Detection.
chapter 13 is dedicated to NDT reliability and the ways the probability of detection can be measured and employed to establish inspection. ASTM's nondestructive testing standards provide guides for the appropriate methods and techniques used to detect and evaluate flaws in materials and objects without destroying the specimen at hand.
Such tests include radiographic, ultrasonic, electromagnetic (eddy-current), X. Active thermography methods enable structural investigations of reinforced concrete elements taking into account many different testing problems.
The goal of this review is to provide an overview on the state-of-the-art regarding the use of active infrared thermography (IRT) for detection and characterization of defects in reinforced by: Proc. SPIENondestructive Inspection of Aging Aircraft, pg 2 (3 December ); doi: / The COPVs covered in this guide consist of a metallic liner overwrapped with high-strength fibers embedded in polymeric matrix resin (typically a thermoset) (Fig.
1).Metallic liners may be spun-formed from a deep drawn/extruded monolithic blank or may be fabricated by welding formed components. Designers often seek to minimize the liner thickness in the interest of weight reduction.
Optical non-destructive testing (NDT) has gained more and more attention in recent years, mainly because of its non-destructive imaging characteristics with high precision and sensitivity. This paper provides a review of the main optical NDT technologies, including fibre optics, electronic speckle, infrared thermography, endoscopic and terahertz by: These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at University of San Diego, San Diego, CA, on July 27 to August 1, The Review was organized by the Center.
Amongst emergent methods, it is worth mentioning Shearography and Electronic-Speckle-Pattern-Interferometry (ESPI), which are used for detection of subsurface defects in thin structures.
Both methods are based on holographic interferometry, by comparing a reference image with the image taken when the material is under by: 1. This chapter provides an overview of current laser-based sensing techniques and their applications in science and engineering.
The chapter first introduces the principles of lasers, followed by a technical description of several laser-based sensing techniques including laser interferometry or electronic speckle pattern interferometry (ESPI), digital shearography, scanning photogrammetry, laser Author: Y.F. Ji, C.C. Chang.

Complete kit includes a hand-held impact indenter, an illuminated 60X measuring microscope, batteries, test block, hardness conversion calculator, instructions, and carrying case.
A hand-held impact indenter drives a 1/16" diameter carbide ball into the sample. Wall et al  have considered probability of detection (POD) data in industrial applications and suggest that could be benefits from the use of simple POD generator models validated against experimental data with a more structured and standardised approach to the use and correction of POD data (using expert judgement, modelling and signal.

Overall it is proved that TOFD has high probability of detection (POD) compared to RT. Small flaws of 4mm*4mm*mm is almost not possible to get through normal RT and UT.
REFERENCES 1. Abstract. Coatings, as most industrial products, must be tested at the Research and Development stage, in production environment, but it should be kept in mind that coating properties depend strongly on both the spray conditions and powder used and both must be regularly tested.
While books on the medical applications of x-ray imaging exist, there is not one currently available that focuses on industrial applications.
Full of color images that show clear spectrometry and rich with applications, X-Ray Imaging fills the need for a comprehensive work on modern industrial x-ray imaging. However, detection of delaminations is a challenging task because of different properties of dissimilar materials and possible complex geometry of the object.
The objective of this investigation is delamination detection using ultrasonic non-destructive methods and numerical study of. Optical Engineering (OE) publishes peer-reviewed papers reporting on research, development, and applications of optics, photonics, and imaging science and engineering.
