Identification, Quantification and Detection of Substances and Targets Using HYPER-CAM

The Telops Hyper-Cam (Figure 1) is a remote sensing instrument delivering unprecedented performance through the combination of high spatial, temporal, and spectral resolution. This sophisticated standoff infrared hyperspectral imaging system is a versatile instrument performing remote detection, determination, and quantification. It is also suitable for field measurements.

Figure 1. The Telops Hyper-Cam

The Telops Hyper-Cam provides characteristic spectral features of solids and gases by modulating the incident infrared radiation from the scene using a Michelson interferometer. This is followed by recording a high resolution spectrum at each pixel of a focal plane array (FPA) detector (Figure 2). The comparison of the measured spectrum against reference spectral signatures of known solids and gases allows for identification of the constituents of a target.

Hyper-Cam Product Line

Telops offers an array of Hyper-Cam products covering the entire spectral range. The Hyper-Cam Long-Wave (LW) is ideal for characterization of materials, minerals, and gas clouds at ambient temperature. The Hyper-Cam Mid-Wave (MW) is typically employed for characterization of target signatures, smokestacks, combustion, and gas clouds at a temperature warmer than ambient temperature. The inclusion of a portion of the shortwave infrared spectral range enables the Hyper-Cam Mid-Wave Extended (MWE) to cover an extended spectral range. Characterizing high-temperature events such as combustion and detonation is one of the applications of the Hyper-Cam MWE. The Hyper-Cam MW and MWE are offered in a «Fast» version that integrates a high speed FPA. The Hyper-Cam sensor data rate is extremely fast and its only limitation is the FPA readout time at a specific spectral resolution.

Airborne Platform

The use of an airbone platform (Figure 3) with the Hyper- Cam allows for generating hyperspectral maps of the ground monitored from an airplane. The airborne module comprises a stabilization platform, an image motion compensation mirror, a navigation module, a Global Positioning System/Inertial Navigation System and all the required airborne operation software. Hyperspectral mapping applications include geology, mining and oil and gas exploration; agriculture and vegetation surveys; surveillance; environmental monitoring; and target detection and identification.

Robust Software

Real-time detection and identification software (Figure 4) is ideal for analyses involving gas leaks and releases. Detection algorithms enable the chemical imaging of multiple gases concurrently on an interactive interface. Reveal is robust research software (Figure 5) for advanced users, performing data acquisition with an optimum flexibility. Reveal Calibrate executes radiometric calibration, whereas Reveal Viewer enables browsing hyperspectral datacubes efficiently. All hyperspectral data acquired can be readily processed with Matlab and ENVI software.

Hyper-Cam Key Benefits

The Hyper-Cam delivers an unprecedented image quality using the 320 × 256 pixels FPA detector. Using different optics, it is easier to modify the 5.1° FOV. With a superior spectral resolution, the Hyper-Cam can very well resolve the spectral features of the targets with good selectivity. The spectral resolution is user-selectable from 0.25 cm-1 to 150 cm-1. The Hyper-Cam records hyperspectral datacubes as function of time, enabling characterization of time-dependent events such as combustion and gas cloud dispersion. As measurement time changes with acquisition parameters, the Hyper-Cam records dynamic events rapidly. The combination of low noise equivalent spectral radiance (NESR) and automated high efficiency calibration sources provides unprecedented accuracy at all times.
