本人小白，在做照相機(jī)鏡頭組的點(diǎn)擴(kuò)散函數(shù)。 'dn]rV0(C  
發(fā)現(xiàn)當(dāng)調(diào)整不同的物距（即Obj的厚度不同）的時(shí)候生成的PSF的形狀和參數(shù)沒有發(fā)生變化。 *WuID2cOI  
請問這是怎么回事呢？ `EaLGzw  
w(L4A0K[  
使用Zemax計(jì)算的PSF，是這個(gè)鏡頭組從前焦平面到成像平面的PSF嗎？是與物距無關(guān)嗎？ :=Nz}mUV  
還是其他的別的原因？ ')cMiX\v

照例說物體不同深度處的PSF應(yīng)該是不同啊

It should change better check these: XwJ7|cB
