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)字光盤(pán)信息存儲(chǔ)中的典型聚焦誤差探測(cè)方法。
Design of optical systems of long focal length, wide field and minimized size has long been the focus of discussion.
大視場(chǎng)、長(zhǎng)焦距、小體積是空間光學(xué)系統(tǒng)設(shè)計(jì)研究的熱點(diǎn)。
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(shí)際應(yīng)用，將會(huì)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(jī)小型化，減小其體積和重量。
