The Cheetah-640-CL camera is the fastest InGaAs infrared camera in the world.
High speed imaging is taking pictures at a high frame rate using a short exposure time. High speed imaging in the visible spectrum covers many applications. For example in automotive crash test analysis or studies of supersonic motion of flying bullets.
Typical high speed imaging applications often require SWIR or MWIR imaging. We offer cameras that generate more than 300 (MWIR) or 1700 (SWIR) frames per second at a resolution of 640x512. Even higher frame rates are possible when using a small region-of-interest within the full frame of 640x512 pixels.
MWIR cameras are used as high speed radiometric and thermal cameras. For example in thermal signature detection, tracking or analysis of aircrafts, missiles or rockets. Thermal tracking of fast moving objects, like missiles, benefits from the addition of a high speed SWIR camera. Thermal cameras detect hot gasses and thermal plumes easily, but SWIR cameras offer more detail and resolution when imaging the (cooler) metal body or debris.
High speed SWIR cameras find application in free-space optical communication systems. These systems are based on Nd-YAG 1.06 µm or eye-safe 1.55 µm lasers. High speed SWIR cameras are used to track communicating transceivers to maintain optical links, or as a wavefront sensor in satellite communication systems. These wavefront sensors are part of an adaptive optics system. They take the larger optical link distances in free space communication into account by correcting for atmospheric distortions.
High speed infrared cameras need to have high sensitivity levels as the exposure times will be small. Next to this, they need to have the highest possible frame rates and the ability to go to small regions-of-interest (ROIs) to increase frame rates even further. Synchronization via an external trigger connector can also play an important role.
We offer the Cheetah-640-CL, the world's fastest SWIR camera. It has a frame rate of 400 Hz up to 1730 Hz in full resolution, which even can be windowed down to further increase the frame rate. And by using its trigger in- and output you can fully finetune the camera to your application.
