關(guān)于衍射極限
bM W|:rn
zemax手冊(cè)里有這么一句話，If the peak to valley OPD is less than one quarter wave ,then the system is said to be diffraction limited. 7iB!Uuc
請(qǐng)問(wèn)這里的peak和valley是指的誰(shuí)的？OPD又是指的誰(shuí)的OPD？是一個(gè)光點(diǎn)發(fā)出的不同光線的OPD嗎？還是理想波面和實(shí)際波面的光程差（也就是波相差吧）？ 請(qǐng)大神明示�。。。� yOM/UdWq
