Abstract

A high precision laser screen dispersion measurement method based on a large area triangle light-screen composite was presented to solve the difficulty of location dispersion test for super-high firing rate barrage weapons. A design scheme for large area triangle photoelectric switch system composed by a laser

a laser beam shaping system and a laser detector array was given

the measuring principle of double large area triangle light-screens was analyzed

and an algorithm for triangle light-screen impact point coordinates was derived. By combining with the output characteristics of the detection device in the system

the algorithm error was analyzed. The analysis results show that maximum theoretical error increases by 0.275 mm

from 0.557 mm to 0.832 mm when the width of regular target area increases from 3.6 m to 10 m. The results of the test show that when the resolution of detector array is 1.6 m

the maximum

error of output coordinates is 0.747 mm

and the maximum

error of output coordinates is 0.635 mm

which shows a high precision measurement for the location dispersion of super-high firing rate barrage weapons. This measurement method is characterized by a larger screen area

higher test precision and easy to install and debug.
