It had equidistantly divided spectral bands and, compared with its previous generation, double the TDI (time-delayed-integration) capacity – to 10 line per band.
Underneath the filter is a ‘2/3inch’ 2,048pixel image sensor from AMS – the CMV2000 which operates at up to 340frame/s at full resolution.
Multiple regions-of-interest can be defined on the sensor – allowing the sensor to be operated at full spectral resolution or to select specific bands to reduce its data rate, increase frame-rate or reduce noise.
“By integrating thin-film filters monolithically onto the AMS sensor, unlike set-ups that place separate optical elements between the lens and sensor, the design guarantees an exceptional filter to detector alignment and is resistant to shocks, vibrations, and temperature fluctuations,” said Imec.
Filter application is via a Buhler Helios 800 optical deposition tool, Imec told Electronics Weekly, which said: “The optical tool was qualified by Imec in collaboration with Buhler to be CMOS compatible. [It] reduces the sensor-to-senor central wavelength variability by a factor of three, with a remaining variability considerably smaller than the filter’s full-width at half-max.”
The sensor is available off-the-shelf for individual purchase units, or supply agreements can be signed for larger quantities, according to Imec.
Applications are foreseen in satellites monitoring food systems, agriculture, biodiversity, water quality, air quality and mining.
