  1. The common path defocusing 4f shearing interferometer in the system was constructed, which is fit for the dense plasma measurement. the advantages of this system consist in its stability and easy adjustment as the common path system and respective adjustability of shearing amount and stripe spatial frequency as m - z interferometer as well

    設計了基於共光路結構的離焦4f剪切差分干涉儀,該干涉儀同時具有m - z型干涉儀的剪切量和條紋空間頻率分別可調的優點以及共光路結構的穩定性和易於調節的優點,使得在稠密等離子體的測量中,系統參數可以兼顧小的剪切量和大的條紋空間頻率。
  2. The field distribution and propagation properties in sil system is analysed, and the relationship between the focusing spot size and the defocusing amount is also described. moreover, a novel model is proposed on basis of the fdtd analysis that can make us increase the distance between sil and recording medium without decreasing the recording density

    模擬的過程中還發現,在小尺寸sil透鏡(半徑為波長量級)離焦時,系統焦點可以被推移到離sil底面較遠的位置而不會產生大的解析度損失,根據該結果我們提出了一種增大sil底面與存儲介質間距的方案,該方案對于sil高密度光存儲系統的實用化研究具有重要意義。
