摘要(中) | 本論文為研究真空鍍膜中以光學監控方法(optical monitoring method)來監控光學薄膜的問題,一般在真空中薄膜厚度的即時量測是以石英晶體振盪方式作間接監控以及光學監控兩種方式。石英振盪監控是以薄膜設計的物理厚度為數值根據,作薄膜蒸鍍時厚度的控制,而光學監控主要取其蒸鍍薄膜之光學厚度,因此,光學膜厚計是常用來直接監控精密的薄膜蒸鍍。
然而,光學薄膜的元件經常是以傾斜角度作光學修正處理,一般光學監控的系統都以垂直入射光來作薄膜光學控制,必須先除以餘弦角度的數值預估薄膜每層的厚度而失去直接監控薄膜的優點,因此,本論文即是研究再以傾斜光線入射作監控補其不足,以達到傾斜光學薄膜元件能以直接監控的方式作精密蒸鍍的控制。在此論文中除了角度需修正之外,也需對色散(dispersion)現象所造成的誤差做修正。最後,再以ZnS及MgF2作多層膜的設計下,改變其各折射率及物理厚度,探討各改變量的影響。

摘要(英) | The study is an optical monitoring method for depositing optical thin films. In general, a quartz monitor and an optical monitor are used to control thickness in deposition process. The quartz monitor indicates and controls the physical thickness of the thin film that is designed before the deposition. Moreover, the optical monitor can control the film at its optical thickness directly. So that, the optical monitoring method usually be used to fabricate the precision optical coating element.
But, the oblique optical element usually is used in photo-electronic system. The optical film must be designed at the oblique angle, but the coating system deposited the film, which the optical thickness is predicated by divided by a cosθ, with optical monitoring at straight angel. Therefore, the monitoring method must be improved by the monitoring light at an oblique angle. With the oblique-incidence optical monitoring, the optical film, then, can be controlled directly in precision coating procession. Except that the angle needs to revise in the thesis, that need to revise the error caused of dispersion too. Finally , and then make under the design of the multi-layer with ZnS and MgF2, change its each refractive index and thickness of physics, fabricate into the influence each changing quantity.
