Cubert-Beitrag in der Laser+Photonik 4/2013
The innovative optical setup of Cubert´s hyperspectral cameras allows the monitoring of fast processes and highly mobile applications. The Cubert UHD 185 was featured in the new edition of the Laser Photonik.
Benefits of hyperspectral imaging
A hyperspectral camera gathers much more data about an object than a normal RGB-camera. Instead of three channels per pixel you get over a hundred. Therefore the non-visible spectral area of the near-infrared and even the middle infrared spectrum is reached. The data obtained gives information about the chemical composition and the structure of an object. With your corresponding pre-knowledge you can achieve real chemical imaging. For example you can determine the chlorophyll content of plants or the oxygen content in blood.
State of the art
There are two established technologies for measuring spectral imaging data. The classical approach is the multi-spectral imaging which has a small number of channels and does not produce real spectral imaging. From a number of 20 channels the line-by-line scanning comes into play. But it takes a few seconds up to a couple of minutes depending on the capturing rate.
Innovating spectroscopy
The technology developed by Cubert is able to generate a full frame hyperspectral cube in milliseconds! In contrast to the complexity of a scanning device, working with Cubert´s >UHD< series is similar to the handling of normal snapshot cameras. A useful mobility is given because of the short integration times of under 1 ms for generating full frame hyperspectral cubes. New fields of applications are opened because the camera and the object can be in motion while taking shots. Depending on the signal-to-noise ratio frame rates from more than 20 Hz can be realized. Fast processes can be quantified by a full frame hyperspectral imaging…
