The deployment of the WIYN One Degree Imager (ODI) was delayed due to issues with the production of its Orthogonal Transfer Array (OTA) detectors. OTA detectors allow moving charge in the detector area during an ongoing science integration to compensate for image motion caused by either telescope guide errors or atmospheric turbulence. In 2011 a small experimental foundry run with a modified design has yielded at least 14 devices that meet science requirements for conventional static imaging mode. Active correction of telescope guide errors by the detectors will be achievable with some precautions during operation, whereas atmospheric motion correction will remain limited to a technical demonstration due to persistent amplifier glow.
In this poster we describe the characteristics of these devices and present a plan for the deployment of ODI with a partially populated focal plane (pODI) at the WIYN telescope in the second half of 2012. pODI will be used to characterize the performance of the ODI instrument and will be used for science operations while the future development options for OTA detectors are considered.
