Active Thermography Using Cellphone Attachment Infrared Camera
Active thermography (AT) is a widely studied non-destructive testing method for the characterization and evaluation of biological and industrial materials. Despite promising applications of AT in industry and medicine, commercialization and wide-spread adaption of AT has long been impeded by the …

Surface Velocity Measurements at the Aeolotron by Means of Active Thermography
… in the wind-wave facility Aeolotron by means of thermography. An active thermography method was used to create heat patterns, which were visualized by an infrared camera. In contrast to other methods, this approach is a non-invasive method and does not disturb the surface properties. Several …

Investigation of the water-sided shear layer at a wind-driven wavy surface by active thermography
A local, active thermographic measurement method was advanced and used for measuring the mean viscous shear stress in the water-sided boundary layer of a wind driven air-water interface in the presence of water waves, at low wind speeds up to u 10 = (4.8 ± 0.3) m/s. Higher wind speeds of up to u 10 …

Visualization of Near-Surface Flow Patterns for Air-Water Gas Transfer
… results are qualitatively compared to data from active thermography (heat, Pr ≈ 7) and boundary layer imaging (gas, Sc ≈ 600), showing a close resemblance of the flow pattern. With higher Schmidt number of the tracer, the structure becomes more pronounced and higher sensitivity to surface …

An investigation of the excitation frequency dependent behavior of fiber reinforced epoxy composites during vibrothermographic inspection
… in fiber reinforced composites during vibrothermography, the use of active thermography with a mechanical excitation for the nondestructive evaluation of a structure or part. Two models, one where the size and geometry of the flaw control a local resonance and the other where the part or …

Quantitative and Qualitative Evaluation of Dental Structures using Multispectral Photothermal Diagnostic Techniques
… These results hold importance as other active thermography methods such as eTC-PCT have not achieved similar outcomes. This makes multispectral TC-PCT a promising approach for expanding its applications in imaging both hard and soft tissues, provided the appropriate wavelength is …

Improvements in Liquid Composite Moulding through Assessment of Process Parameters
… of variables and process parameters requiring active measurement and control, achieving high quality simultaneously with low cost and variability has proven an elusive target for LCM processes. Although the effects of many parameters and variables have been studied and understood, others have …

BIOACTIVE-RICH MUSHROOMS FOR FOOD REFORMULATION
… of plant-based protein sources, with bioactive-rich mushrooms (BRMs) emerging as a frontrunner. Extracts and powders of BRMs are widely used as dietary supplements and functional foods, particularly in Eastern countries, due to their high nutritional value: abundant dietary fiber, …
