New PixelCam Cameras Capture Real-Time SWIR Multispectral Images
MUMBAI, December 20, 2012 /PRNewswire/ --
Shortwave Infrared "Snapshot" Imager Offers New Options for Biomedical Imaging and Security
Ocean Thin Films has introduced PixelCam™, the first commercially available "snapshot" multispectral cameras for shortwave infrared (SWIR) analysis from 700-1700 nm. The cameras harness SWIR's powerful imaging by simultaneously acquiring four or more standard and custom spectral bands with a single camera, enabling extraction of spectral information not noticeable with panchromatic SWIR devices. This feature makes the PixelCam especially useful for applications in biomedical imaging, process control and high-contrast security and surveillance environments.
The breakthrough to provide these compact multispectral camera platforms is combining PixelTec's precision micro-patterned optical coating technology with robust SWIR area sensor cameras manufactured by Sensors Unlimited of UTC Aerospace Systems. High-transmission dichroic filter arrays are aligned directly over corresponding pixels in the imaging array for optimal spectral and spatial resolution. Standard PixelCam cameras come preconfigured with three and four bands, and custom cameras are available with additional application-specific bands - providing greater versatility and contrast than traditional multi-sensor devices.
"PixelCam makes this sophisticated multispectral SWIR technology - which used to be limited to highly specialized projects - now much more accessible, portable and practical for all kinds of research and production applications," said Randel Mercer, Vice President of Business Development for Ocean Thin Films. "Its unique pixel-level filters make PixelCam the first commercial 'snapshot' camera that can be customized and scaled for your specific multispectral application."
At the heart of each PixelCam multispectral camera is a custom filter array integrated into a solid-state InGaAs imager with a full resolution of 640x512. Its sturdy platform provides simultaneous 12-bit Camera Link® digital and RS170 analogue outputs and an external trigger. The form factor, frame rates, operating temperature and power requirements are unchanged by the passive spectral filters - enabling easy integration into handheld, mobile, and aerial devices.
