幫助中關(guān)于光柵的計(jì)算幫助時(shí)這樣寫(xiě)的 r.@UH-2c  
Radial Polynomial Grating. The radial polynomial grating type is essentially a DOE defined by a rotationally symmetric phase profile. The phase profile is given by the following 20th order equation:[/td][/tr][/table] ?l[#d7IB  
[table][tr][td][/td][td=1,1,100%] ;=%cA#}_0  
The phase computed by the above equation is in lens units. The derivative of the phase gives the grating period at any point on the surface. The second order term (coefficient C1) gives the basic focal length of the DOE, with the focal length equal to: IN;!s#cl:

這里是把光柵相位當(dāng)做一個(gè)單獨(dú)的光學(xué)屬性，那徑向半徑r是怎么帶入計(jì)算的，是把這個(gè)屬性設(shè)置在某一個(gè)面上后再自動(dòng)獲取這個(gè)面上的徑向半徑嗎 ZQR)k:k7  
如果是這樣，那如果設(shè)置在導(dǎo)入的三維文件的面上時(shí)，系統(tǒng)又是怎么獲取徑向半徑來(lái)計(jì)算的
