Characterization of the Teledyne CHROMA HgCdTe Detector for Imaging Spectrometers

Imaging spectroscopy places high demands upon detector
performance. The dynamic range, linearity, and sensitivity
must be maintained at high frame rates, and artifacts must
be minimized across large focal plane array (FPA) formats. In
this contribution, we discuss the Teledyne CHROMA HgCdTe
FPA in the context of imaging spectrometer applications. The
FPA was characterized in a laboratory thermal-vacuum chamber
that allowed the read noise, dark current, well capacity,
linearity, and crosstalk to be measured. Results are presented
across a range of operating temperatures and pixel clock rates.
Additionally, the outcomes of radiation testing to 100 krad TID
are discussed. The results of these characterizations are critical
to the designs and performance predictions of future imaging
spectrometers utilizing the HgCdTe CHROMA FPA.
