A Miniaturized Active Thermography System to Inspect Composite Laminates [PDF]
IEEE Transactions on Industrial Informatics, 2021 With the rapid increase of the integration and complexity of industrial components, the inaccessibility and inapplicability of existing nondestructive testing devices have become a bottleneck for in situ inspection of these objects. This article introduces a miniaturized active thermography system featured with a small-size, low-resolution, and low ...

Pre-detection of microplastics using active thermography
Chemosphere, 2021 Spectrometric analysis is one of the most widely used approaches to characterize the chemical nature of microplastics. Despite recent developments, this key step remains time consuming. The aim of this paper is to propose a new method for the pre-detection of microplastics based on mid-infrared imaging.
