As presented in the theoretical part, an array sensor, composed of InGaAs, could produce images of a scene with poor visibility such as a scene with haze, fog and zc2500. This technology could be used by the firefighters for seeing through the smoke during an intervention. A high-pass filter was added to the optical system of the FLIR camera for selecting the wavelengths comprised between 0.

The sensitivity bandwidth is comprised between 0.

Newer Post Older Post Home. The experimentations, realized in October,show that persons are still detectable through artificial fog at indoor and outdoor conditions.

For example, hairs are more reflective in Fir spectrum.

September th, Toulouse, These results are in agreement with previous works [3][4]. The nightglow phenomenon allows also producing an image by night. This test was done fkir indoor in a room of 15m2.


Fflir observe in Figure 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 duration of test is nine minutes.

As shows in Figure 3, the maximum radiant of nightglow in SWIR spectrum is similar at the radiant measured at 0. This test was done at outdoor in a garden composed of trees, grass and one path.

This technology provides also a strong visibility at dusk and dawn hours. For this test, we used a fog machine which can produce 40m3 of artificial fog per minute. Concerning video analytics, SWIR imaging allows detection, recognition and identification of objects and persons. Rameshwar M September 27, at 9: Image Analysis and Processing.

A pass-band filter was added to the optical system of the FLIR camera for selecting the spectrum centered at wavelength around 1. In this work, the sc5200 was simulated by machines.

The duration of test is 30 minutes.

Volumepp Another interesting point is that the phenomenon of nightglow, which is a very weak emission of light in the upper atmosphere, is xc2500 radiant in SWIR spectrum.


In conclusion, SWIR imaging allows using algorithms designed for analyzing visible images [2].

Differences in appearance between the visible and SWIR images are due to reflective material properties. For this test, we used a fog machine which can produce m3 of artificial fog per minute. Visible and SWIR streams were recorded from both cameras: The results are presented below. The SWIR imaging is used in perimeter surveillance for seeing through fog, haze, dust and smoke.

A future experimentation would consist in generating images in SWIR spectrum of scenes with smoke in real conditions. In video analytics, the SWIR imaging has advantages for extracting and locating features by using algorithms designed for visible spectrum. Moreover, if the artificial fog is too dense 3 flit, the two persons in the background are only detectable in IR image 3.
