HySpex SWIR-384 hyperspectral camera from NEO, is developed for field, laboratory, airborne and industrial applications. The state of the art MCT sensor with cooling down to 150K yields low background noise, high dynamic range and exceptional SNR levels.
With a max frame rate of 400 fps, combined with an aberration- corrected optical system with high optical throughput (f/2), the data quality, speed and sensitivity is truly state of the art.
A wide range of close-up lenses allows the use of the camera at working distances ranging from a few cm with a spatial resolution of 53 µm to infinity for e.g. airborne remote sensing.
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.
