Leuven, Belgium, 27 October, 2015 – Xenics, Europe’s leading developer and manufacturer of advanced infrared imagers, cameras and customized imaging solutions from the LWIR to the visible realm, introduces a new leading version of the Cheetah-640-CL. The new 800 Hz version features a significantly higher speed than what is standard available on the market and interfaces easily to any frame grabbing system via medium CameraLink. The camera has been designed for applications where high speed imaging in the SWIR band matters. Whether for adaptive optics, spectral analysis, tracking of fast and hot objects, electro-coalescence, on more.
Xenics offers a complete flexible-to-use SWIR camera
Users of high-speed applications need very flexible camera equipment to follow the different conditions they may encounter. The new Cheetah-640-CL 800 Hz SWIR camera fills the gap between the already available 400 Hz and 1730 Hz versions of the Cheetah-640-CL. “The main advantage of the 800 Hz version over the faster 1730 Hz, is the ability to output 12 bit images via a standard CameraLink medium interface, which connects easily to any frame grabbing system”, adds Raf Vandersmissen (CEO sInfraRed – a Xenics company). The TE1-cooled sensor makes the Cheetah-640-CL highly sensitive, achieving low dark current characteristics at flexible integration times from 1 μs up to 40 ms @ 25°C sensor temperature (high gain mode); or up to 100 ms @ 268K sensor temperature (high gain mode).
The use of high speed SWIR imaging
The laser beams used for free-space satellite communication emit typically at 1064 nm or 1550 nm (eye safe and low atmospheric attenuation). The high-speed feature of the Cheetah-640-CL camera is being used in adaptive optics systems to correct imaging systems for atmosphere turbulence.
Since astronomical observations are also prone to atmospheric turbulence, adaptive optics techniques are also being used. Observations in the NIR and SWIR are specifically interesting because of the absorption bands of CO2, H2O and a number of trace gases. Moreover, airglow emission in SWIR can be detected from several planets. The combination of adaptive optics and a high-speed Cheetah-640-CL camera is key to achieving diffraction limited observations.
Cheetah-640-CL has already proven to be a very valuable tool in electro-coalescence research for water separation from heavy crude oil. The Cheetah-640-CL camera can obtain well above 1000 frames per second at 640×512 resolution, enabling a detailed investigation of the high speed water drop coalescence process in visually non-transparent crude oil.
