Research On Test Technology Of Intersection Laser Accuracy Optical Target

The projectile’s firing accuracy measurement is one of the important contents during the range test, and it decides the ability of a weapon can hit a target, in recent years, the firing accuracy testing of projectile has received much attention all over the world. The existing accuracy test equipment are always expensive and complicated, therefore, it is very necessary to study a new technique of accuracy target in range target measurment field.In this thesis, a new accuracy target testing method has been designed, a intersection type laser detection screen is set up by using semiconductor laser as light source, and photistor array as light-sensitive component, cooperated with intersection algorithm, the projectile’s position can be get. Firstly, the testing principle of intersection laser accuracy optical target is introduced in this thesis, then some key technique and solution is put forward, such as sensitivity, frequency response and signal acquisition and extraction, the correctness of them are proved by experiments. There are five parts to introduce the intersection laser accuracy optical target research.1) The principle of the measurement; 2) Mainly raises and realizes some key techniques which can not be evaded; 3) Mainly introduces the needs and choice of some key devices or component, the design principle of the circuit, and the flow process of the signal; 4). The design of the whole structure, it mainly accomplish the brief mechanical structure design, which can support the target; 5) Error analysis, trough the software simulate the target screen and confirm it can meet standard.The technique of laser accuracy optical target is verified by the simulation analysis and experimental research, the optical accuracy target in this thesis has such advantages, the optical path is reasonable, and the circuit is simple without amplifier circuit but can realize digital signal processing, the error analysis made by mathematical model shows that the designed intersection laser accuracy optical target can meet the test requirements, it provide a new method of accuracy testing measurement in range target measurment field.
