Struggling in world's competitive markets, industries are attempting to upgrade their technologies aiming at improving the quality and minimizing the waste and cutting the price. Industry tries to develop their technology in order to improve quality via proactive quality control. This paper studies the possible paint quality in order to reduce the defects through neural network techniques in au...

Non-contact, remote monitoring of thickness and drying progress of a paint film is required in fields of non-destructive testing and evaluation. For rapid image acquisition of 2D cross-section in paint film, we propose a terahertz (THz) paintmeter based on real-time 2D THz tomography, which is achieved by a combination of electro-optical time-to-space conversion and line focusing of a THz beam ...

We propose a paintmeter for noncontact and remote monitoring of the thickness and drying progress of a paint film based on the time-of-flight measurement of the echo signal of a terahertz (THz) electromagnetic pulse. The proposed method is effectively applied to two-dimensional mapping of the painting thickness distribution for single-layer and multilayer paint films. Furthermore, adequate para...

The ability to measure the thickness of paint on graphite/epoxy composite structures directly would be of benefit in the aerospace industry. The weight reduction would increase fuel mileage for the airline customer. An additional reason for reducing the thickness of paint on graphite/epoxy composites is not as obvious as the weight savings. A concern in the use of composite structures has been ...

In past years, it was known that paint on reflector surfaces causes degradation of antenna gain and noise temperatures, but it was not known how much degradation occurs as a function of paint and primer thickness or frequency. This article presents an approach used to study the properties of paint by first measuring the complex dielectric constants of paint and primers at frequencies of interes...

Polymer-ceramic pressure-sensitive paint (PC-PSP) has been investigated as a surface-pressure sensor for unsteady aerodynamics and short duration measurements. This PSP provides a fast response to a change in pressures with a spray-coating ability. Because it is sprayed onto an aerodynamic surface, the thickness of PC-PSP may play an important role in determining the performance of this sensor....
