Deep sub electron noise readout in CCD systems using digital filtering techniques
CCD spectroscopy dark matter sub electron noise
2011/9/28
Scientific CCDs designed in thick high resistivity silicon (Si) are excellent detectors for astronomy, high energy and nuclear physics, and instrumentation. Many applications can benefit from CCDs ult...
Application of speckle and (multi-object) multi-frame blind deconvolution techniques on imaging and imaging spectropolarimetric data
Sun: photosphere – Sun: spectropolarimeters
2011/9/27
We test the effects of reconstruction techniques on 2D data to determine the best approach. We obtained a time-series of spectropolarimetric data in the Fe I line at 630.25 nm with the Goettingen Fabr...
