DALSA (Waterloo, ON, Canada) announced expanded imaging capabilities including backside illumination (BSI) in custom image sensors for aerospace applications in earth observation and remote sensing.
The company says that scientists and researchers have been using DALSA's multispectral, hyperspectral, and high resolution panchromatic sensors to obtain the highest quality imaging data possible to guide science and resource policies in government and industry. With successful delivery of these specialized devices for applications including environmental assessment (land, water, pollution, agriculture), aerial mapping, and defense and security (reconnaissance and guidance), DALSA says it is ready to offer new capabilities to a wider audience.
DALSA says its multispectral sensors build on its linescan and TDI devices, which provide maximum signal-to-noise ratios and sensitivity. New technologies in multispectral filters allow DALSA to capture images from not only the traditional RGB visible color bands but also a number of near-infrared bands in a single highly compact and cost effective package. Custom backside thinning capability enables the highest quantum efficiency.
DALSA also has the ability to tailor the bands capture to the needs of the application and provide solutions on a cost effective and timely basis. As most multispectral sensors are deployed aboard satellites or airplanes, DALSA has developed techniques to allow these sensors to withstand the extreme harshness of these environments, including extreme vacuum and temperatures, over the multi year life of these products. DALSA’s experience with ultra-high resolution devices allows it to deliver multispectral linescan imagers with more than 12,000 horizontal pixels in each band.
In addition to multispectral sensors, DALSA offers hyperspectral sensors, typically 2-D area arrays sampling a higher number of even narrower bands. Custom backside thinning (BST) process enables the sensor to collect as much light as possible so that each wavelength can be assessed to measure trace quantities of compounds in the environment. The company offers both CMOS and CCD technologies to the unique needs of hyperspectral customers.
