If the hot surface is smaller than the field of view of the infrared detector, not so much energy enters into the opening of the infrared detector as would be possible under full illumination.
如果热表面比红外探测器的视场，没有那么多的精力小全光照下进入到作为有可能红外探测器开幕。

It will be used in the illumination system of high power semiconductor laser over a long infrared distance of 100 meters through adjusting an additional geometric optical lens.
然后通过调节外加的几何光学透镜，在长达100米的红外远距离大功率半导体激光器照明系统中将得到利用。

The infrared focal plane detector based on a TDI-CCD has the features of high sensitivity and high resolution. It can operate at a lower illumination condition and will have a wide application area.
