The Hyper-Cam from Telops is a hyperspectral imaging camera (Figure 1). It facilitates generating hyperspectral maps of an area monitored from an airplane when installed on Telops’ airborne platform. This article presents the key technical specifications, features and benefits, and applications of the Hyper-Cam.

Key Features and Benefits
The high sensitivity and outstanding signal-to-noise ratio of the Hyper-Cam enable detecting weak signals. The spectral resolution of the Hyper- Cam is flexible, thus allowing users to select any value up to 1cm-1 and thereby yielding tens to hundreds of spectral bands. Mapping and targeting are the two acquisition modes. The Hyper-Cam can be used for both ground and airborne applications. Besides yielding georeferenced data, it acquires visible images concurrently with IR hyperspectral data. The Hyper-Cam is compatible with longwave (8-12µm) and mid-wave (3-5µm) Hyper-Cam sensors.
Applications
The Hyper-Cam is used in the following applications:
- Agriculture and Vegetation Surveys – The Hyper-Cam can easily perform soil and vegetation characterization in large areas.
- Environmental Monitoring – Airborne hyperspectral data facilitate the simultaneous detection and determination of multiple substances. The Hyper-Cam Airborne is an important instrument for environmental monitoring applications, detecting pipeline leaks, and analyzing substances in urban pollution.
- Geology, Mining, and Oil and Gas Exploration – A Hyper-Cam Airborne can be used for mine face imaging to map the mineral content of a mine face and determine mineral concentrations and streaks (Figure 2). Airborne detection of natural gas leaks allows for the exploration of vast areas.
