就是波長跟凹縫的大小一樣或小於波長時，光波無法確實反射表面的特性(好像也不是這個)

這讓我想到開光罩時用超短波UV的目的..]]>Aug 27th 2008 8:39AMhttp://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/http://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/市面上那種換成藍光也只是換個感覺 滑鼠上的表現跟一般紅光led相同
重點應該還是廣角鏡]]>Aug 27th 2008 12:45PMhttp://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/http://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/那是雷射好些
或是bluetrack好些呢....]]>Aug 27th 2008 8:56AMhttp://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/http://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/雷射採用反射波長作為滑鼠移動的依據, 相當於瞎子摸象.
光學採用實際影像作為滑鼠移動的依據, 相當於用眼睛觀察.
所以, 雷射滑鼠可以偵測細緻桌面, 而光學滑鼠不能.
不過當雷射滑鼠在非常光滑的表面時, 例如鏡面, 一樣沒有辦法動作. 光學滑鼠由於採用影像辨識, LED投射一來是為了照亮桌面, 二來是斜光產生桌面紋理, 增加CMOS判讀的能力, 所以即使是鏡面, 只要表面有圖騰, 光學滑鼠還是能動作, 反之, 雷射滑鼠形同瞎子, 有無圖騰都是死.
有興趣的人可以拿一張白的相紙和有影像的相紙做比較, 雷射滑鼠的表現都一樣, 但是光學滑鼠會有很大的差異.]]>Aug 28th 2008 12:23AMhttp://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/http://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/不知道可不可行？？
畢竟NB可以帶著到處跑～

會很不習慣的]]>Aug 27th 2008 2:43PMhttp://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/http://chinese.engadget.com/2008/08/27/this-is-microsoft-bluetrack-mouse/主要還是有效反射/散射訊號的訊雜比要高吧。

200mm 以上的通常都不會有大光圏....
