It is suggested that logarithm transform of oscillograph and large dynamic rangeofdetector should be applied to adjust the optical cavity for improving metrical precision.
在光路调节中采用具有对数变换功能的示波器和动态范围较大的探测器，可以提高测量精度。

Those creatures have long had four-color vision, but a key difference is that their fourth type of color detector is in the high-frequency ultraviolet range, beyond where humans can see.
这些动物早已拥有四色觉，但关键的区别是，他们的第四种颜色位于高频的紫外线区域，在人类可视范围之外。

If the input signal is anywhere in the frequency rangeof the detector, the meter will make a valid power measurement.
