Research On Reflecting Low-light Sighting Telescope Resolution Testing System

Low-light sighting telescope has the unique feature of recognizing objectives in the night. Because of this unbeatable effect in a war, to probe and develop the feature is underlined by each of those strong military power countries. At the mean time, various optical performance accreditations relating to Low-light sighting telescope has gradually emerged. The resolution testing is the most powerful quality assurance judgment. The research on Low-light sighting telescope resolution testing system is an integral part. and a thorough analysis and design to the whole system. which gives evidence to the testing in a full scale.With the extensive application of the low-light sighting telescope, ways to test the functions are continuing renovated. In this essay, it mainly emphasizes the research on the composition of the resolution testing system. As the Low-light sighting telescope should be operated under the night sky light condition, collimating lenses that are mainly used to observe the condition provides simpler condition simulation standards than other functioning reference index. In addition, each of the composition functions and reference indexes of the testing system have been introduced:discusses the standards of the resolution target plate; designs the collimating lenses that are being used under the whole pack of the system. They are all applied under a subjective testing ways and analyzing principle. The analysis above takes on a detail and deep reference evidence for the low-light sighting telescope.
