🔥 Introduction to Multimodal Chemical Imaging
In the world of mechanical engineering and thermal sciences, obtaining precise information about materials at the molecular level is vital for developing industrial processes and improving materials and systems. Here the importance of photothermal spectroscopic scanning and Raman techniques emerges, as multimodal chemical imaging methods provide a deep understanding of material composition in non-destructive ways.
Modern techniques such as O-PTIR and Photothermal SRS (PT-SRS) represent a qualitative leap that enables the integration of measurement and analysis of infrared interactions with Raman scattering, in addition to fluorescence imaging to determine the properties of living and non-living materials with high accuracy reaching submicron limits.
🔧 Modern Imaging Techniques and New Developments
O-PTIR, or infrared photothermal spectroscopic imaging for measuring submicron regions, offers unprecedented ability to detect material composition and distribution within samples without the need for contact or destruction. This technique allows simultaneous monitoring of the infrared system and Raman measurements at the same time.
On the other hand, Photothermal Stimulated Raman Scattering (PT-SRS) is a technique based on stimulating Raman scattering using thermal laser pulses, which increases the sensitivity and precision of chemical analysis in nanostructured and microscale materials.
In addition, fluorescence imaging techniques are used to provide an additional layer of information about chemical distributions, especially in biological samples, where molecular movement and physical state can be identified with high efficiency.
🚗 Practical Applications in Mechanical Engineering
Advanced techniques such as O-PTIR and PT-SRS open new horizons for material analysis in fields related to mechanical engineering, especially in:
- Inspecting composite materials and alloys used in engines and turbines.
- Analyzing corrosion characteristics and thermal damage in thermal power systems.
- Understanding fluid dynamics in HVAC systems through chemical imaging of solutions and oils used.
- Development and innovation in manufacturing precision parts that require micrometer-level accuracy or better.
Thanks to their ability to analyze samples without contact, multimodal spectroscopic scanning systems can monitor materials under actual operating conditions, which enhances preventive maintenance and reliability capabilities in industrial facilities.
🏭 ICORS 2026 Conference: An Innovation Platform for Mechanical Technologies
As part of supporting continuous development in chemical imaging technology, Photothermal Spectroscopy Corp. announced that it will host a workshop during ICORS 2026 in Istanbul, which will highlight the practical uses of the latest multimodal imaging systems.
The workshop lasts two hours on 23 August 2026, and includes technical lectures covering:
