红外无损探测技术已在各个方面得到广泛应用,其所使用的主要设备为一台测温仪或一台热象仪。一般情况下,上述两种设备都无法用来测量高速旋转物体表面的真实温度。根据热象仪的光机扫描原理,热象仪在扫描空间一场的过程中,行扫从上而下(或由下而上)的逐条扫过整个空间,当被扫目标在高速旋转时,就不可能获得一幅静止的象。一般对于高速扫描的热象仪,由于扫描频率高,而一般的活动目标又远远低于这个速度,所以可用来观察一般的活动目标,即可从图象上见到目标的活动规律,然而对于这种目标的运动速度是有一定的限制的。对于人眼观察目标来
Infrared non-destructive detection technology has been widely used in all aspects, the main equipment used by a thermometer or a thermometer. In general, neither of these devices can be used to measure the true temperature of a rotating object at a high speed. According to thermal imager scanning principle, thermal imager in the process of scanning a space, the line sweep from top to bottom (or from bottom to top) sweep the entire space one by one, when the sweep target is rotating at high speed , It is impossible to obtain a still image. Generally for high-speed scanning thermal imager, because the scanning frequency is high, and the general target of the activity is far below this speed, it can be used to observe the general activity of the target, you can see from the image of the target activity, however There is a limit to the speed at which this goal can be achieved. For the human eye to observe the goal
