November 2007 — Xenics’ latest release (Q4/2007) of its high-end, power PC-based, high speed imaging system Cheetah is an InGaAs focal-plane array camera that covers the standard SWIR (short wave infrared) wavelength area 0.9 to 1.7 μm – with all control and communications circuitry in one housing. Cheetah offers a high resolution of 640 x 512 pixels at a maximum full frame rate of 1730 Hz; in reduced region of interest mode, more than 100,000 fps are possible. The new release will be demoed by Xenics at Vision (6-8 Nov. 2007, Stuttgart, Germany, Hall 2/Booth C52).
Xenics’ new high-speed, power PC-based Cheetah for the SWIR (0.9 to 1.7 μm) features a 640 x 512 pixel InGaAs array. This InGaAs detector features a new Xenics ROIC (Read-Out Integrated Circuit) optimized for high speed with 16 outputs and a 40 MHz pixel rate. The Cheetah camera includes a graphical user interface that provides direct access to various camera settings, such as exposure time, region of interest and gain. Moreover, a fast and easy non-uniformity correction (2 point) procedure is available. The camera’s power PC allows for a data interface based on the TCP/IP gigabit ethernet protocol and more advanced correction procedures. Alternatively, also a CameraLink data interface is foreseen.
The new Cheetah camera can be operated in two modes: a) stand-alone; using the on-board memory (up to 16 GB) for extremely fast data acquisition. At 1730 full frames per second, the recording time is limited to 15 seconds. b) continuous streaming; using a PC and the CameraLink data interface for continuous data streaming (frame rate is limited by the CameraLink interface speed).
The new Cheetah digital camera is equipped with 14-bit ADCs and is operated from a single 12 V/5 A power supply (included in the delivery). A C-mount fixture allows the use of all standard optical lenses. A medium speed version of the Cheetah (400 fps maximum) will also be available.
With this advanced, user-friendly configuration, uniquely combining extreme high speed, high resolution and best sensitivity in a reliable InGaAs array, the new Cheetah is perfectly suited for high speed imaging in the SWIR range for a variety of applications (medical, R&D, wavefront sensing, etc…)
