The SC NIR complements FLIR’s range of products for R&D and automation applications to include: scientific research, imaging spectroscopy, astronomy. For scientific studies, R&D and critical processes, Flir Systems Inc. has announced its model SCNIR (near-infrared) camera. The fully. FLIR is the world leader in the design, manufacture, and marketing of thermal imaging infrared cameras.
The sensitivity bandwidth is comprised between 0. For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. The duration of test is nine minutes. For example, hairs are more reflective in SWIR spectrum.
Image Analysis and Processing. Volumepp The nightglow phenomenon allows also producing an image by night.

A future experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions. This test was done at outdoor in a garden composed of trees, grass and one path. In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images .
As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0. Moreover, if the artificial fog is too dense 3the two persons in the background are only detectable in IR image 3. As presented in the theoretical part, an array sensor, composed of InGaAs, could produce images of dc2500 scene with poor visibility such as a scene with haze, fog and smoke.

This technology could be used by the firefighters for seeing through the smoke during an intervention. Rameshwar M September 27, at 9: The SWIR imaging is used in perimeter surveillance for seeing through flit, haze, dust and smoke.
A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0. Differences in appearance between the clir and SWIR images are due to reflective material properties.
These results are in agreement with previous works . We observe in Fllir 5 that the person disappears in the fog in the visible image while the same person is still visible in the SWIR image 2. The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.
Newer Post Older Post Home. In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum. September th, Toulouse, This test was done at indoor in a room of 15m2.
The results are presented below. Another interesting point foir that the phenomenon of nightglow, which is a very weak emission of light in the upper atmosphere, is more radiant in SWIR spectrum. This technology provides also a strong visibility at dusk and dawn hours.
Visible and SWIR streams were recorded from both cameras: A pass-band filter was added to the optical system of the FLIR camera for selecting the spectrum centered at rlir around 1. The duration of test is 30 minutes. Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons.
For this test, we used a fog machine which can produce m3 of artificial fog per minute.
