A review of night vision metrology is presented in this paper. A set of reasons that create a rather chaotic metrologic situation on night vision market is presented. It is shown that there has been made a little progress in night vision metrology during last decades in spite of a big progress in night vision technology at the same period of time. It is concluded that such a big discrep- ancy between metrology development level and technology development can be an obstacle in the further development of night vision technology.
