The utilization of specialized Infrared cameras consisting of infrared sensors to capture and develop the image of an object constitutes the process of thermal imaging. Our eyes detect visible light; however, the thermal radiation being emitted in the infrared region can only be detected by the cameras used for thermal imaging.

This article explores how key optical methodologies are applied to inspection, metrology, and analysis at various stages of semiconductor research, development, and volume manufacturing.
Infrared spectroscopy is a powerful analytical tool that was pioneered in the early 20th century. It analyzes samples by exploring interactions between matter and electromagnetic radiation in the infrared region. Today, the technique is used in both quantitative and qualitative analyses in a wide range of industries to study the chemical and molecular properties of a substance.

With advanced resolutions reaching sub-angstrom levels, electron microscopy provides direct visualizations of catalyst particles, support structures, and pores that complement spectroscopic and diffraction methods. When integrated with elemental analysis techniques, a comprehensive picture of catalytic systems can be built up from the microscopic level.
