对比度

However, if the spectrum distribution of the objective in the field is different, and its difference mainly reflected in a fix band with different monotone, then, the goal of identifying the object could be done by changing photosenser response band and enhancing the contrast of object and background.

但是若视场中的目标具有辐射光谱分布差异，且其光谱分布差异主要体现在某一固定波段具有不同的单调性，那么可以通过有选择地改变光电传感器的响应波段，来提高目标与背景的对比度，从而也可以达到辨识目标的目的。
