Abstract
Future mission studies will be expecting Hubble-class resolution and extremely wide areal coverage in order to provide the best science return per investment dollar. The only way to combine high resolution imaging with wide areal coverage is to design large FPAs with very small pixel plate scales. The design and construction of a modular imager cell (MIC) using embedded controllers to ameliorate the power, mass, and cost for the large format CCD focal plane arrays, can provide a robust, low-risk, high-reward solution to mitigate possible mission failures by providing a way to assemble large FPAs using a modular “plug and play” solution. By placing the detector and the associated readout electronics on a single module, one can easily remove and replace any single module without adversely affecting other detectors in the FPA. We present a prototype design and results for an MIC for use with a delta-doped LBNL 3.5k × 3.5k CCD. This prototype design is comprised of the CCD preamplification circuitry and CCD control signal filtering circuitry and is scheduled for flight in an upcoming sub-orbital rocket payload.
