SWIR, or short-wave infrared, is light invisible to the human eye but detectable by specialized infrared imaging lenses and cameras. The SWIR spectrum is an ideal choice for a variety of applications, including solar cell inspection, security, and biomedical imaging. Ra'ef Mikhail, Optical Engineer, demonstrates the benefits of a SWIR imaging system compared to a traditional visible system by recreating a popular scene from Star Wars®. It is clear to see that the SWIR system can discern the two characters in a foggy environment, whereas the visible system cannot detect them at all.
Hi, my name is Ra'ef Mikhail. I am an engineer at Edmund Optics. I am going to show you today the advantages of imaging with a SWIR camera over a visible camera. And it's going be imaging through smoke at a scene from a popular sci-fi movie. As you can see, it becomes completely opaque to the visible eye and to the visible camera. But at the same time, for the SWIR camera, it's completely visible and you can actually make out the features of those two strange characters in the back of the scene. Well, I mean, the applications are really countless. It starts all the way from medical industry to the defense industry to the fun industry. More in things like surveillance, where you can actually detect heat from things that are hiding behind bushes or leaks in nuclear power plants, for example, in pipes and what not. For example, silicon wafers look like a mirror to us humans but for a SWIR camera, it actually looks completely transparent. It is practically a window and that is helpful because you can detect cracks and fissures in the product in the semi-conductor industry and that is one way to detect it over trying to visually see it on a mirror. Again, my name is Ra'ef Mikhail, I am an Optical Engineer with Edmund Optics. This was a short demo on SWIR capabilities and the SWIR camera. Please check us out at DSS and www.edmundoptics.com.
