术语和定义

GB/T13962-1992确立的以及下列术语和定义适用于本标准

3.1

工业检测型红外热像仪industrialinspectingthermalimager

适于工业领域使用的，通过红外光学系统、红外探测器及电子处理系统，将物体表面红外辐射转换

成可见图像的设备。它具有测温功能，具备定量绘出物体表面温度分布的特点，将灰度图像进行伪彩色

编码。简称“热像仪”。

3.2

视频信号的信噪比(S/N)videosignaltonoiseratio

热像仪正常工作时，信号电压的峰一峰值和噪声电压均方根值之比。

3.3

噪声等效温差(NETD)noiseequivalenttemperaturedifference

热像仪观察一个低空间频率的圆形或方形靶标时，当其视频信号的信噪比((S/N)为1时，目标与背

景之间的等效温差。NETD是评价热像仪探测目标灵敏程度和噪声大小的一个客观参数。

GB/T19870-2005

3.4

空间分辨力spatialresolution

热像仪分辨物体空间几何形状细节的能力。它与所使用的红外探测器像元面积大小、光学系统焦

距和像质、信号处理电路带宽等有关。一般也可用探测器像元张角(DAS)或瞬时视场来表示。

此参数通常可近似计算得出:空间分辨力=(2nX水平视场角度(“”/(3600X水平像元数)，单位
