But if larger dispersionwave exists in system, the enhancing of PSA's gain must be larger.
但是，如果系统中色散波较大，放大器增益的微调量也相应较大。

Microcomputcrs automatically control infrared grating monochrometer through interface circuit, and make a precise measurement of zero dispersionwave length for optical fibre material.
微机通过接口电路自动控制红外光栅单色仪，对光纤材料进行零色散波长的精确测量。

Unlike a normal lens, which compresses or changes the actual shape of a light wave through diffraction, a time lens magnifies or compresses the time of a light wave through dispersion.
