What is high speed imaging?
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.
What is high speed imaging used for?
Xenics 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 Xenics 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.
What features are needed?
- High Frame Rate - We offer frame rates up to 1730 Hz in SWIR and 460 Hz in MWIR. Our cameras can even be faster when you reduce your region of interest.
- Short Exposure Time - A short exposure time is necessary in high speed imaging to reduce image blur.
- High Thermal Sensitivity - Thermal cameras need to have a high sensitivity level (low NETD) to detect the smallest temperature differences.
- Large Dynamic Range - An IR camera with a large dynamic range covers a large temperature area
- Low Read Noise - Low read noise results in high sensitivity for low light signals.
- Digital High Speed Interface - A digital interface like CameraLink, GigE or CoaXPress is necessary to assure reliable and fast data transfer.
- Trigger Interface with Low Jitter - A trigger interface with low jitter is a necessity for high speed applications to synchronize the camera.
What do Xenics Infrared Cameras offer?
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.
