Security & Surveillance
Atmospheric turbulence, visibility through fog can be better approached with a higher wavelength in the SWIR Band.
SWIR – A new way of sensing for Defense & Security
SWIR is considered by many as one of the most versatile technology for the defense & security sectors. Bringing valuable information such as the ability to identify or recognize a target (e.g: compared to MWIR & LWIR band), it brings also a better vision through harsh weather conditions (fog, smoke).
With a low readout noise and a High Dynamic Range, NIT SWIR cameras, e.g: WiDy SenS, can cope with the challenging requirements of the Defense and security area.
Gated Imaging
GATED IMAGING provides the ability to image a specific depth slice of a scene. Applications are multiple, including observations through obscurants (severe weather conditions), estimation of distance, and localization of obstacles (drone detection with background suppression). Imaging devices must be fast enough to cope with the reflected light.
NIT’s SWIR cameras offer at the same time, precision with the shortest effective exposure time, the shortest rise time, and the highest dynamic range on the market enabling to cover a broad number of situations in the field, and any applications, including yours.

Image Fusion Thermal/ I-CMOS
Wide Dynamic Range
Several issues can be encountered in this domain that can impair a clear vision of the scene:
Low light sensors have limited capability to see below 10mLux. NIT I-CMOS sensor can see down to less than 0,7mLux (overcast night).
EMCCD is power-hungry and prone to saturation when high illumination light is present in the scene. NIT I-CMOS, thanks to the log response, considerably decreases the halo. The sensor allows extracting information near or inside it.
LWIR thermal imager is poor for identification. By combining low light and Wide Dynamic Range, NIT I-CMOS is the best in class identification technology with a visible image.
Direct view intensified products have some limitations in fusion imaging. NIT proposes standard and custom digital solutions for combining night vision images with LWIR or low light.
In sum-up, NIT I-CMOS solutions allow a unique value proposition through contrasted images at any night light levels.
