Research On The Modern Testing System Of Magnification Of Gun Optical Sighting Telescope

Gun optical sighting telescope is used to advance shot probility of light armament firing dynamic target,small target and far distance target, improve tactic usage performance of light armament,add productors of light armament tactic range of usage.To be a basic parameter of gun optical sighting telescope,the judge of magnification influences the whole performance of the optical sighting telescope.According to traditional testing principle and method of magnification of gun optical sighting telescope,it used to adopt optical principle and technique,use subsidiary visual equipment to implement testing reading,it is not only influenced by human factor but also easily fatigue,influence testing precision.Aimed at the modern requirement about testing principle and method of magnification of gun optical sighting telescope, in the basis of analyzing lots of traditional testing principle and methods ,put forward a modern optical testing principle and method based on CCD image system,optical technique,auto control technique and computer image processing technique.According to the testing principle,we conduct overall structure design.Because of adopting photoeletric autofocusing technique and computer image processing,the the testing precision and efficiency is greatly improved.Experiment prove,the testing efficiency less than or equal to one percent.
