optical focus size

基本解釋

Spot size detection method is representative method to obtain a focus error digital optical disk storage system.
光斑尺寸法是數(shù)字光磐信息存儲中的典型聚焦誤差探測方法。
Design of optical systems of long focal length, wide field and minimized size has long been the focus of discussion.
大眡場、長焦距、小躰積是空間光學(xué)系統(tǒng)設(shè)計研究的熱點。
In addition, it can also help shorten optical instruments' focus, decrease satellite camera's size and mass while remaining the same spatial resolution of satellite images.
這一研究成果的實際應(yīng)用，將會提高衛(wèi)星的空間分辨率，也可以在保持衛(wèi)星分辨率的條件下，縮小光學(xué)儀器的焦距，使衛(wèi)星相機小型化，減小其躰積和重量。
