optics n.〔作單數用〕光學。

optimal

We are used to calling an instrument of this kind in optics a telescope, and the radioastronomical counterparts are therefore briefly named “radio telescope“ . 在光學上我們通常稱這種類型的儀器叫望遠鏡,因而射電天文學上的對應物簡稱為“射電望遠鏡”。

The term “spectrogram“ is borrowed from optics . “聲譜圖”一詞是從光學借來的。
