為什么設(shè)計(jì)一個(gè)光學(xué)系統(tǒng)時(shí)最終用zemax優(yōu)化后顯示其誤差函數(shù)值只有0.02(MF)左右,算是很小了,但是其MTF傳函卻非常差,下降的很厲害,而運(yùn)用analysis 中的image simulation輸入測(cè)試圖片后,成像效果比較不錯(cuò)(即使在大視場(chǎng)高頻區(qū)),因而比較迷惑,望高手指教,謝謝!

回 樓主(a1234) 的帖子
MF值只和你設(shè)定的誤差函數(shù)中所包含的項(xiàng)目、目標(biāo)、權(quán)重有關(guān),與MTF值不見(jiàn)得
有直接對(duì)應(yīng)關(guān)係。 |

MF值與MTF之間無(wú)必然聯(lián)系 與設(shè)定有關(guān) 謝謝 呵呵

depending on what you defined in MF, if it's MTF related opernads then the sampling used both MF and the anslysis will have an on the calculated value. Plus, not sure what spatail frequency range you are looking at on the analysis window and the one you are optimizing against in the MF...
