固定频率栅格畸变测试卡
1)可选新尺寸
2)可计算成像系统的畸变
3)本产品的精度通过NIST认证
尽管在测量应用方面畸变会带来一定的麻烦，但是您必须清楚事实上关于被测物体的各种信息并没有丢失，仅仅是物体所成的像放错了位置而已。采用本测试卡，您可以很方便的测量出畸变当量和精度。使用斑点（或质心）分析测量软件就可对斑点中心定位。为了扩充图象分析软件应用功能，我们推出了固定频率以及可变频率的测试卡，固定频率的测试卡可应用在3个标准方式选项，每种有不同的斑点尺寸/斑点频率相结合，根据您的视场角或分辨率/精度等要求来选择合适的畸变测试卡。玻璃上面镀铬或是乳色测试卡上面镀铬的测试卡可以获得，它们可以来满足您对透射或是反射方面应用的需求。包装上附NIST可追踪查询认证码，遵循MIL- STD-45662A标准。
