SIGIS 2 • Long Distance Identification, Visualization and Innovation with Integrity

The SIGIS 2 is a scanning imaging remote sensing system based on the combination of an infrared spectrometer with a single element detector and a scanner system. It allows automatic identification, quantification and visualization of gas clouds from long distances. The system measures a selected area and visualizes a chemical image overlaid on a video image as a result of the automatic analysis. SIGIS 2 systems are applied in industrial facility surveillance, environmental applications, atmospheric research, and volcanology and are part of the equipment of emergency response forces around the...

The Scanning Infrared Gas Imaging System SIGIS 2 comprises of a Fourier transform infrared (FTIR) spectrometer with a telescope and a rotating head. Inside this 360° rotatable head, a scanning mirror and a camera are positioned for fully automatic surveillance of the environment. Scanning Infrared Gas Imaging System SIGIS 2 with a schematic illustration of its working principle. The large optics inside the spectrometer provide high optical throughput that enables the fast measurement of ultra-low noise infrared spectra without the need of an active IR source. The telescope reduces the field of...

OPUS RS To measure a certain area of interest a selection is made directly in the video image inside OPUS RS. The selected area is scanned and in each scanning mirror position an infrared spectrum is measured. The measured spectra are analyzed automatically and an alarm is generated in case a target compound is identified. The position of identification is indicated by an overlay of the analysis result on the scene image. The compound can easily be located and the analysis result can be interpreted intuitively: In the example shown on the right, the measurement of ammonia in the exhaust of an...

Application Due to its capability to automatically detect and quantify gases even in a continuous 24/7 measurement mode, the SIGIS 2 can cover a broad range of applications. Among these are the surveillance of industrial facilities, environmental and atmospheric applications and academic research, such as in volcanology as well as the detection of gases for safety and security applications. As such the SIGIS 2 is also part of the equipment of emergency response forces around the world to detect and visualize potentially harmful gases released at disasters or accidents as well as to observe high-profile...

Tomography By measuring a gas cloud with two SIGIS 2 systems under an angle, as shown in the picture on the left, a three-dimensional cloud model can be derived within OPUS RS by means of a tomographic reconstruction. The cloud position, as well as its dimensions can be calculated and gas concentrations can be determined from the column densities. The 3-dimensional cloud model derived in OPUS RS can also be opened in a geographic information system (GIS), such as Google EarthTM for further visualization. Measurement setup with two SIGIS 2 systems around a potential release point to determine...

Plant Surveillance with SIGIS 2 Industrial plants can be observed by one or multiple SIGIS 2 systems for the fast detection of leakages and disaster prevention. To operate the systems from a remote control-center the systems can be connected using fiber optical cables to span large distances. If several SIGIS 2 systems are used for the simultaneous surveillance of a large industrial facility, the single systems can be integrated via a dedicated local network. In the exemplary setup shown below, all information can be accessed through a main PC in the plant control-center. Optionally, the data...

The SIGIS 2 is part of the equipment of emergency response forces around the world to identify and visualize potentially harmful gases at disasters or accidents or to observe high-profile events, such as political summits or international sports events. Due to its ruggedized construction and special shock absorbing mounts the SIGIS 2 can be operated in helicopters and motor vehicles. Additionally to toxic industrial compounds (TICs) also chemical warfare agents (CWAs, optional) can be detected and visualized from long distances. Permanent installation of a SIGIS 2 system in an emergency vehicle...

SIGIS 2 systems are also used for the surveillance of high-profile events such as international sports events. SIGIS 2 at a DFB cup final in the Olympic stadium in Berlin. Accessories: (1) To optimize the line of sight, a tripod for elevated and levelled positioning is available. (2) Mobile power supply for field operation of more than six hours. Can also be used as uninterruptible power supply (UPS). (3) For the secure vehicle integration a shock mount frame is available. (4) A ladder mount enables mounting the SIGIS 2 on aerial ladders of fire emergency trucks.
