炸点平均高度线扫描 CCD 柱面镜曲线拟合 mean height of burst line scanning CCD cylindrical lens curve fitting

摘要

为了准确测量远距离炸点平均高度, 采用了双线扫描 CCD成像的方法并建立了测量系统理论模型。首先采用了望远式成像光学系统对远距离炸点进行成像, 采用柱面镜进行成像变换; 采用 Zemax软件对成像光路进行了模拟, 模拟点列图结果表明了系统在物距为 20 m时, 能够在 5 m范围内有效测量炸点光的平均高度。最后, 采用曲线拟合的方法求出光斑中心位置并对测量系统进行了线性标定。经实验验证本测量系统可以在物距为 20 m处测量炸点的平均高度最高约为 3 m, 测量精度可以达到 1.95%。所设计的炸点平均高度测量系统满足了远距离、大范围的测量要求, 系统运行稳定、可靠, 采用双线阵 CCD的测量方法有效的消除了物距不能确定的影响。

Abstract

In order to measure the mean height of long distance burst, a double line scanning CCD measurement system is established and its theoretical model is built.First, telescopic optical system is used to image the burst, and the image is transformed by a cylindrical lens.Then, Zemax software is used to simulate the optical system, whose spot diagram show that the system can effectively measure the mean height of burst within 5 meters at a long distance of 20m.Finally, the spot center is acquired by means of the curve fitting and linear calibration is carried out for uncertain parameters of the system.Experimental results indicate that the maximal height is 3 m approximately at a long distance of 20 m.The mean error is 1.95%.The presented system can reach the acquirement of long distance and wide range.Furthermore, the uncertainty of distance can be eliminated naturally by using the double line scanning CCD system.
