4.0 Multiple Output CCD Optimization . ... For the reasons described in the section above, we are rapidly approaching the limits to decreasing the noise spectral density of on-chip CCD amplifiers using smaller amplifier geometries. ... Our testbed for optimizing multiple output CCDs is our ADAPTIII CCD – a very high frame rate (10,000 frames per second), low noise (less than 3 electrons rms.), back illuminated CCD designed for adaptive optics and wavefront sensing applications. ...
