monochromatic source meaning in Chinese

单色光源
单色源

By far the most nearly monochromatic source available at present is the laser .
目前可用的最接近单色光的光源是激光器。
This direction finding algorithm may resolve uncorrelated monochromatic sources , but it assumes that all signal frequencies are distinct . it requires no a priori knowledge of the signals " frequencies , suffers no frequency - doa ambiguity , and pairs automatically the x - axis direction cosines with the y - axis direction cosines
该算法用单矢量水听器，在无需知道信号先验信息的条件下，可以实现对多个不相关信号的方位角估计，并且不受频率模糊度的影响，自动匹配x轴、 y轴的方向余弦。
