| 摘 要： | 为了消除由非致冷红外焦平面自身温度变化造成的辐射测温偏差,提出了一种基于G-t(黑体辐射灰度-探测器工作温度)标准曲线进行辐射测温的新方法.该方法从热辐射理论和热像仪测温原理出发,利用实验测得的G-t标准温度关系曲线,并结合灰体表面真实温度的计算公式,最终实现了非致冷红外焦平面成像系统的高精度辐射测温.实验结果表明,当...

| Abstract: | In order to eliminate the measurement deviation caused by the temperature variation of an uncooled infrared focal plane array,a new radiation temperature measurement method based on the standard G-t(Gray level detected from a blackbody-Temperature of an infrared detector) curves is proposed.According to the thermal radiation theory and the temperature measurement principle of a thermal imager,the standard G-t curves measured in the experiment are combined with the real temperature formula for a graybody.Fin... |
