请问如合用oslo edu进行非球面光学元件设计？



<P>大家好,请教一下请问如合用oslo edu进行非球面光学元件设计？</P>
<P>在oslo中的哪些参数可以体现非球面特性？</P>

ad,ae,af,ag,or as2,as3,as4,as5,as5...

<P> 麻烦Jobyan能不能说得清楚一点，我刚刚学不太懂</P><P>谢谢！</P>

<P>非球面的形狀可以把它分解成多項式來描述，如果是旋轉對稱的話，</P>
<P>可以寫作 Z=aR^0 + bR^2 + cR^4 + dR^6.....</P>
<P>其中 這些 a, b, c, d, ...就是你要去optimize的參數</P>



ykcheng 发表于 2004-4-18 23:53:00



<P>這是最常見的形式，在OSLO裡叫做Standard Asphere</P>
<P>其中cv是radius的倒數，cc是conic constant</P>
<P>ad, ae, af, ag 都是係數</P>

<P>這是General Asphere, 為旋轉對稱</P>
<P><img src="data/attachment/forum/dvbbs/2004-4/20044181555566.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'data/attachment/forum/dvbbs/2004-4/20044181555566.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
</P>

ykcheng 发表于 2004-4-18 23:59:00

<P>這是Asphere (all orders)</P>
<P><img src="data/attachment/forum/dvbbs/2004-4/200441815593240.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'data/attachment/forum/dvbbs/2004-4/200441815593240.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

谢谢ykcheng的热心帮助，我还想问一下，oslo edu版应该怎样优化，他跟其他版本不太一样。

ykcheng 发表于 2004-4-20 01:02:00

<P>抱歉我只有用過Premum版的，不過我想基本原則都是一樣的，EDU版只是功能少一些，</P>
<P>比如說非球面的形式比較少，但是最常見的Standard Asphere應該會有。</P>
<P>你可以在variable裡面加入ad, ae, af, ag , 然後在設定operand, 可以先用OSLO內建的Spot Size/Wavefront。</P>
<P>通常每次引入一個變數在慢慢增加會比較好。也就是先設ad, Iterate幾下後在加入ae, 再Iterate之後再加入af.....</P>

EDU不提供这些方法，只提供GENII,OR RAY ABBERATION

谢谢ykcheng和dfjss.

hbjtyxl123 发表于 2004-4-27 01:25:00

<P>   请问ykcheng,怎么設定operand，里面的DEFINITION,   MODE,   WGT,   NAME参数意义分别是什么？这跟优化有什么关系，不是variable之后选择误差函数（例如GENIIERROR FUNCTION)，然后SHIFT+F9就可以了吗？</P><P>   什么叫OSLO內建的Spot Size/Wavefront，它有什么用？我怎么找不出阿。</P><P>   谢谢解答！</P>
