Next: CCD Scientific Performance Up: CCD Operation Previous: CCD Operation . A visible light photon releases only one electron-hole pair, and consequently many photons must be collected in each pixel for a measurable signal to be produced. ... This use as an imaging X-ray spectrometer requires that no more than one photon is incident on each pixel in any image frame, which imposes a requirement that image collection times be limited to ~seconds for typical astronomical applications. ...

... Back-illuminated CCDs with resolution greater than 4096 x 4096 elements, frame rates in excess of 10,000 frames per second, and noise lower than 3 electrons rms. have been independently demonstrated. Additionally, back-illuminated CCD cameras have been shown well suited for significant low light level imaging applications. However, the application of back-illuminated CCDs for night vision applications requires that all performance characteristics be optimized in a single manufacturable device. ...
