(1) Code V中計使用 eva (oal s1..i z1)計算鏡頭長度時是把像面離焦量包含在內(nèi)的。 SV2M+5#;
(2) 使用movie.len,計算其三個變焦位置的總長如下 aFS,GiB
(OAL Z1 S1..I) = 107.522580166499 ~])t 6i
(OAL Z2 S1..I) = 107.568305499122 v

(OAL Z3 S1..I) = 107.525471335228 5u*-L_
不一樣長。拿掉離焦量 gK[YQXfTy

再計算一次總長如下 A'jP7P
(OAL Z1 S1..I) = 107.554580166499 bdQ_?S(
(OAL Z2 S1..I) = 107.542305499122 4cl\^yD
(OAL Z3 S1..I) = 107.544471335228 e>(<eu~P
還是不一樣長。說明此案例在沒有離焦時也無精確保持等長。也可以不用歸零離焦量而直接求得同樣長度如下 tE]= cTSV
(OAL Z1 S1..I)-(CT SI Z1) = 107.554580166499 F.w5S!5Q
(OAL Z2 S1..I)-(CT SI Z2) = 107.542305499122 E0MGRI"me

(3)是的,優(yōu)化時是以離焦面的成像品質(zhì)為準(zhǔn)。 /.Ww6a~
