HySpex VS-725 is a hyperspectral imaging system consisting of HySpex VNIR-1800 and HySpex SWIR-725. Designed to provide high resolution airborne data in the full spectral range from 400-2500 nm, HySpex VS-725 offers a compact and cost efficient solution.
The novel HySpex SWIR-725 configuration provides a high resolution SWIR imaging system of unique optical performance with exceptionally low smile and keystone. HySpex SWIR-725 consists of two HySpex SWIR-384HR (High Resolution) systems, overlapping with one degree in the central FOV, in a common sensor head configuration.
The Data Acquisition Unit provides full control and real time previews from all sensors, and ensures accurate synchronization between the sensors and the INS to achieve high precision georeferencing.
All HySpex cameras can be supplied with a rotation or translation stage, making them ideal for acquisition of hyperspectral images of static scenes, either in the field, in a laboratory or a clinical environment. The scanning is fully integrated in the camera control software.
Typical accessories used as a part of the HySpex laboratory imaging system are:
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.
A typical field system consists of HySpex cameras mounted on a tripod and a rotation stage. Depending on user requirements, various rotation stage and tripod solution can be offered. These range from the standard solutions allowing horizontal scanning of two cameras, to high capacity solutions where tilted scanning is possible, and automated stages scanning the cameras in the XY direction.
Many users combine HySpex with their existing third party sensors, e.g. terrestrial LIDARs.
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.
NEO's airborne HySpex systems have been in operation since 2003
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 conveyor belt using the belt motion for scanning.
Using the VNIR-1024 and 1 meter working distance as an example; the field of view is ~28 cm and the pixel footprint on the conveyor belt is 0.27 mm x 0.56 mm. With these settings and full spectral range and resolution, the maximum speed of the conveyor belt is 46 cm/s. The belt speed can be drastically increased if rectangular pixels are permissible, or by reducing the spatial/spectral resolution.
