| Reviewed the development of the Low Light Level image intensifiers,introduce the difference among the GenⅠ,GenⅡ,super GenⅡimage intensifier.Especially discuss the operational life prediction of Super GenⅡLLL image intensifier.Build the regressive equation of the operational life test by using the regressive analysis and least square method,linearizing the exponent equation through exponent fitting to the linear regressive equation for predicting the operational life of Super GenⅡimage intensifier;then the operational life time of image intensifier was calculated.Besides,the manufacture of a Super GenⅡimage intensifier operational life test set;image intensifiers' light current and cathode sensitivity etc for which high voltage,low level current measurement and calculation;and the solvent for problems during manufacture was introduced. |
