The ODI project is partially funded through the NSF Telescope System Instrumentation Program (TSIP).

The One Degree Imager

The One Degree Imager (ODI) is the flagship of the WIYN Consortium's new instrument initiatives. The combination of its large size and ability for electronic image stabilization make ODI a unique and very competitive instrument. ODI is sensitive to visible light and features a one thousand mega-pixel camera, an impressive number compared to the average digital camera at eight mega-pixels. The camera will cover a one-square-degree field of view which will allow ODI to capture vast areas of sky, greater than four times the area of the full moon, in a single image. A special detector technology called Orthogonal Transfer Array (OTA) CCD will be used to stabilize the images. Using OTA technology, ODI will be able to compensate for image motion due to atmospheric turbulence, telescope shake, and tracking errors by locally shifting the image directly within the CCD.

Detailed information on ODI is available on the ODI Technical Specifications page.

ODI Update


The WIYN Board has approved an upgrade project to add an additional 24 detectors to ODI. The resulting 6x6 detector array will provide a 48 x 48 arcminute field of view, as shown below. New detectors are currently being fabricated.

Additionally, an issue with low light level charge transfer inefficiency has been remedied. More information on the upgrade project can be found on the ODI Status and News page.

Blue tiles indicate locations of the new detectors. Yellow/green tiles indicate locations of the current detectors in pODI. The final configuration is subject to change.
