Electron Multiplying CCDS (EMCCDs)

Electron Multiplying CCDs (EMCCDs) are a very interesting new development with application to astronomy. They offer sub-electron read noise almost independently of read-out speed and thus permit single photon detection at pixel rates > 10MHz. Current applications include adaptive optics wavefront sensing and high frame rate spectroscopy.
