Infrared Thickness Sensor of Paint Film

Measurement of Paint Layer Thickness with Photothermal Infrared Radiometry

Thin Film Thickness Measurement Using Conduction and Infrared Transmission

Many applications in a diverse demographic of engineering fields require knowledge of the thickness of thin films and coatings. An example of some applications for which thin film thickness is critical are semiconductors, optics, and protective coatings. There are various methods for measuring thin film thickness, however, many of them are destructive, or are only capable of measuring thickness...

Terahertz paintmeter for noncontact monitoring of thickness and drying progress in paint film.

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...

Noncontact Terahertz Paintmeter for Real-Time Two-Dimensional Cross-Section Imaging of Paint Film Thickness

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 ...

Paint Curing By Infrared Catalytic Thermoreactors

The standard method of curing industrial coatings has been accomplished by slow open air drying or somewhat faster gas heated convection air ovens. Electric infrared has also been used for curing paints for certain applications. While enhancing the rate of cure, the energy costs become excessive to operate. The introduction of gas fueled infrared catalytic thermoreactors is changing the way ind...
