Abstract

The development of the Orthogonal Transfer Array CCD provides unique control mechanisms that allow a rich set of operating modes necessary to meet the demands of very wide-field imaging programs. The exclusive control modes of the OTA place strong requirements on the CCD controller to support the capabilities of the device while providing detector-limited performance. NOAO and WIYN Observatory have developed a controller based on the MONSOON Image Acquisition concept with the specific application for testing and characterizing the OTA performance and capability. The OTA controller implements control solutions for on-chip cell multiplexing, multiple read modes, high-speed guiding with multiple stars, predictive algorithms for temporal and spatial image motions, and application of electronic tip-tilt corrections. The MONSOON image acquisition system provides the flexibility needed to support the full capabilities of the OTA, while its extensibility can facilitate large mosaics of devices to meet the demands of future very large focal plane instruments.
