Both cameras, VIS 360° and IR 360°, use Time Delayed Integration (TDI) technique to improve light sensitivity. The platform will rotate at 5Hz and provide 5 high resolution 360° degree images per second. The captured image is projected on a native cylindrical format.
This solution has a number of inherent advantages such that discontinuities and non-uniformities in the horizontal plane are non-existent. Changing sunlight levels or even direct sunlight will not restrict view. For Remote Tower operations the relatively low transmission bandwidth is another inherent advantage. The 5 Hz update rate on 100 kHz flicker-free screens highlights the Operators attention to moving objects as planes, cars, animals and clouds. The 5 Hz update rate is more than adequate to obtain similar Operator’s situational awareness as with an Out-The-Window view.
The rotating platform has absolute control on the azimuth angle with a resolution much better than the pixel resolution, and there is no optical distortion in azimuth. This solution gives a very accurate and reproducible angle positioning to an observed object. The 360° Camera System will be aligned with respect to north with accuracy better than ± 1 mrad.
This sensor combined with the offered display solution, will give the operator a real angle perception between objects as they will appear with exactly same separation as in Out-The-Window View of a classic tower. The same as ICAO`s required 20:20 visual acuity.
Both VIS 360° and IR 360° are physically positioned on a rotating table. This is a high performance direct drive servo motor with long life time.
The power, control signals and video is transferred to the rotating table by an inductive-optical slip ring. This ensures that there is no mechanical contact except from the ball bearing. This type of slip rings is provided by several suppliers and is widely used due to long life time and high data bandwidth.
