解釋
抖動模式-
This research is aim at putting forwarding laser wavelength scanning interference testing method. processing and analyzing instantly - read interference pattern corresponding with continuous varying wavelength, the method overcomes the following disadvantage. for example, the longer referenced and measuring optical circuit in big - scale high - accuracy asphere testing, and the sensitive interferential system to the disturb, such as the oscillation of worklable, dithering of air, and so on
研究的目的主要是針對大型高精度非球面面形檢測中干涉儀的參考光路和測量光路較長，干涉系統對工作臺振動和空氣抖動等外界干擾因素的影響敏感，干涉圖不穩定等問題，提出了激光波長掃描干涉測試方法，該方法通過對瞬間讀取的、與連續變化波長對應的干涉圖的處理和分析，克服了上述缺點，為大型高精度非球面的檢測提供了一種適用的方法。 -
