Airborne Applications

The HySpex cameras were from the beginning built for airborne applications. Dedicated software, for controlling up to three cameras in parallel, is delivered with the cameras.

High resolution and high speed, combined with low weight and power consumption, make NEO’s HySpex cameras very well suited for airborne data acquisition.

Position- and attitude logging systems (IMU/GPS) from leading manufacturers can be integrated and supplied with the cameras. Alternatively, the HySpex systems can be interfaced with the customer’s existing navigational hardware.

For airborne systems, NEO supplies dedicated software and a touch screen for ease of operation. A high performance rack computer is standard, but customized light-weight computers are available for smaller aircrafts, UAV's etc.

Using NEO’s VNIR-1600 in an airborne application recording the terrain from 1500 m altitude, the resulting on-ground pixel footprint is 27 cm x 54 cm and across track FOV is 450 m. At this altitude and at maximum frame rate (135 Hz) and resolution, the ground can be scanned with a speed of 263 km/h (142 knots). Under these conditions, it is possible to cover 2 km2/min yielding 4 Gbyte of data pr. minute.

The weight of a HySpex camera plus IMU/GPS for an aerial application is less than 7.5 kg.

Supporting equipment considered mandatory in an airborne hyperspectral imaging system are:

• Airborne Computer
• Touch screen
• Base plate
• Navigation

Optional:

• Stabilized mount
• Mission Planning and Pilot navigation System
• Post processing hardware and software

Field Applications

All HySpex cameras can be supplied with a rotation or translation stage, a feature making them ideal for acquisition of static scenes. The scanning is fully integrated in the camera control software.

Here, the term 'Field System' denotes a HySpex camera mounted on a rotation stage. Examples of field application are:

• Defense and security: Military target detection/-identification
• Geology: Mineral mapping

Industrial Applications

Due to their extremely high acquisition speeds and real-time image correction features, the HySpex cameras are well suited for a wide variety of industrial applications such as material inspection or quality control.

In a typical industrial application, the HySpex camera is mounted statically above a conveyer belt, as shown in the picture below, using the belt motion for scanning.

Using the VNIR-640 and 1 meter working distance as an example; the field of view is ~30 cm and the pixel footprint on the conveyer belt is 0.5 mm x 0.5 mm. With these settings and full spectral range and resolution, the maximum speed of the conveyer belt is 25 cm/s if square pixels are required. If rectangular pixels are permissible, or the spectral range or resolution can be reduced, the belt speed can be increased drastically.

Different industries are today employing hyperspectral imaging:

• Food and nutrition industry
• Paper industry
• Textile industry
• Pharmaceutical industry
• Chemical industry
• Color printing
• Mining
• Waste/recycling

Supporting equipment considered mandatory in an industrial hyperspectral imaging system are also availible.
