abstract |
Hyperspectral imaging has been providing vital information on the Earth landscape
in response to the changing environment, land use and natural phenomena. While conventional
hyperspectral imaging instruments have typically used rows of linescan CCDs, CMOS
image sensors (CIS) have been slowly penetrating space instrumentation for the past
decade, and Earth observation (EO) is no exception. CIS provide distinct advantages
over CCDs that are relevant to EO hyperspectral imaging. The lack of charge transfer
through the array allows the reduction of cross talk usually present in CCDs due to
imperfect charge transfer efficiency, and random pixel addressing makes variable integration
time possible, and thus improves the camera sensitivity and dynamic range. We have
developed a 10T pixel design that integrates a pinned photodiode with global shutter
and in-pixel correlated double sampling (CDS) to increase the signal to noise ratio
in less intense spectral regimes, allowing for both high resolution and low noise
hyperspectral imaging for EO. This paper details the characterization of a test device,
providing baseline performance measurements of the array such as noise, responsivity,
dark current and global shutter efficiency, and also discussing benchmark hyperspectral
imaging requirements such as dynamic range, pixel crosstalk, and image lag. |
