dc.description.abstract | Application of CMOS image sensors with non-destructive readout capability have several advantages over current CCD sensors in detecting Near-Earth Objects (NEOs). They include detection of temporal changes, cosmic ray rejection, no charge blooming, expanded dynamic range, and lower dark current. Since wide field survey usually requires large mosaics, a "rolling shutter" operation simplifies the challenge of large mechanical shutters. Being able to readout parts of the field in destructive mode offers the possibility of providing guiding feedback to the telescope during exposure. We have carried out preliminary testing of a prototype CMOS camera built by Spectral Instruments Inc. on a one-meter telescope on Mt. Lemmon, Arizona as applied to rapidly moving NEOs. We have also demonstrated "post facto" guiding on a known NEO that significantly improves the signal to noise. | en_US |
