Effect of temperature gradient on EBI of image intensifier

摘要

In this paper we give the experiments for the measurement of EBI of an image intensifier with the change of temperature gradient of it. At the same time, we give the curves of EBI versus the different temperature gradients. We show the causes for EBI of an image intensifier with the change of temperature gradient. We conclude, from the calculations and experiments, that there is need for the waiting measurement time for us to minimize the measuremental difference of EBI caused by temperature gradient. The paper provides some scientific basis for improving the objective performance of low light level night vision system in the field.
