So we developed a new tip for the fNIRS fibers-a brush optrode that slides the fibers between the hair follicles.

因此我们发明了一种新的光纤，一种近似梳子的光极，它使得光纤可以在头皮的小囊之间自由地穿梭。

The device is officially known as a “brush optrode, ” which uses that same fNIRS technology, but in a way no other device has been able to up to this point.

这种梳子的学名称之为“梳子光极”，它的原理和近红外光谱法差不多，但是却超越了之前所有的设备。
