photodétecteurs à amplification optique

French to English Science Chemistry; Chem Sci/Eng système de spectroscopie
Good morning,

I either find "optical amplifier or "photodetector" each on its own, so I must be doing somthing wrong here

"Dans un mode de réalisation particulier, ce moyen comprend des photodétecteurs à amplification d'électrons, avantageusement
des photodiodes fonctionnant en régime d'avalanche ou de cascade (APD). Ces photodétecteurs peuvent également être des photomultiplicateurs. Selon d'autres modes de réalisation, ce moyen de détection comprend des photodétecteurs à amplification optique, telles que des caméras CCD ou CMOS refroidies, par exemple à air liquide ou élément Peltier.

According to other embodiments, this detection means comprises optical amplifier photodetectors(?), such as cooled CCD or CMOS cameras, for example with liquid air or Peltier element.

Thank you in advance!

optically amplified photodetectors (photomultiplier)

See http://en.wikipedia.org/wiki/Photodetector for a discussion of the many different types of photodetector. The photomultiliplier is different from photodiodes and other quantum detectors in that a single photon releases a cascade of further photons, ginving an amplification effect. But see also http://ipnpr.jpl.nasa.gov/progress_report/42-128/128J.pdf

I enclosed links for you to verify, if you can, the device you need.
