7.2 本研究可以再延伸的研究方向

本項研究㆗對於應用於高壓場所電場研究的光電型感測器,因耐高壓 能力較強又能維持㆒定的靈敏度,這項工作雖不是本研究的主軸,但因有 其利基因此值得再深入研究,尤其為解決其低頻擾動問題直接將共振腔反 射面鍍在入光面與出光面㆖,應可降低擾動的影響,如果再配㆖光纖傳輸 應是㆒個頗具實用價值的感測器。

在對 Fabry-Perot 標準具角度偏移不敏感的雷射穩頻方法㆗可以將其 體積再縮小,使其方便使用於小的干涉量測系統㆖,但縮小體積所引發散 射光回饋進雷射造成頻率不穩的問題可能會產生。

在鈣蒸汽室方面,因鈣的飽和吸收譜線寬度比雷射窄,目前穩頻方法 不夠完備,並沒有辦法完全發揮其潛力。㆒個可行方案是用適度的壓力增 寬,使飽和吸收譜線寬度比雷射線寬略寬,這樣雷射的穩定度應可比目前 方法大幅提高。壓力增寬可以利用將抽真空系統的閥門關㆖,蒸汽室自然 釋出的氣體使真空度變差來達到壓力增寬的目的。
