20220390313 · 2022-12-08 ·

Methods and systems for detecting container leakage using thermal imaging, for example, infrared imaging, are disclosed. A method may include a step of sensing thermal radiation emanating from a scene encompassing a liquid-holding container. For example, the container may be an intravenous fluid bag. The method may also include a step of generating a thermal image of the scene based on the sensed thermal radiation and a step of analyzing the thermal image by assessing whether the thermal image includes a thermal feature indicative of the presence of leaked liquid outside the container to determine whether a leak exists in the container. In some embodiments, the container may be enclosed in an overwrap. In such a case, the assessed thermal feature may be indicative of liquid being present in an interstitial volume defined between the container and the overwrap.

PHOTOTHERMAL ANALYSIS OF A PART OF SOLID MATERIAL
20220381717 · 2022-12-01 ·

A method of photothermal analysis of a solid piece includes injecting heat into a region of a surface of the piece, called heating region, capturing a thermal analysis image of a detection region which is distinct from the heating region, then subtracting a reference image from the thermal analysis image. The reference image corresponds to a thermal emission distribution as caused by the injected heat for a case where the surface portion of the piece is without defects. Such method makes it possible to reduce an analysis cycle time for the piece, and to reduce a signal-to-noise ratio of images capable of revealing defects present in the surface portion of the piece.
