Research On High Precision Distance Measure Based On Position Sensitivity And It’s Application On Fuse

To meet the demand of high precision detecting of weapon system between bomb and goal, realize high precision cooperation between fuse and warhead, aim at the special using entironment, this paper puts forward a method about measuring distance continuously by laser triangle, which reconstruct the method of triangle measure distance, adopting exact linear array detector as laser fuze receiver, disposeing incepted information of line-array by line-array image element subdivision arithmetic,thus,we can distinguish distance information by incepted facula situation information, initiative optics fuze can measure bomb-aim distance in close quarters.Compare a few methods of laser measure distance, aim at the special using environment, this paper puts forward a method about measuring distance by laser triangle. Analyzed the particularity of emission system, incepting system and optics system corresponding to the method about measuring distance by laser triangle.To realize high precision detecting, researched orientation subdivision arithmetic of linear array CCD.This paper puts forward power ash degree centroid arithmetic by analyzing distributing mode of incepted facula energy and time field change rule of facula energy interspace distributing mode which arosed by fleetly change bomb-aim distance.This method can improve precision of image disposing on the base of real time signal disposing. Construct experiment equipments and do a few experiments. Demarcate the curve by zigzag line approaching method, greatly minish distance error. Lastly, analysed the error. Experiment and analyse result indicate that triangle measure distance method linear array incept and linear array image element orientation subdivision arithmetic can realize the function of high precision detection of fuse.
