【摘要】：電磁全息測量數(shù)據(jù)包含兩種模態(tài),因此重建流動圖像也需采用"雙模"融合的敏感場。首先,通過電磁全息探測物理場分析,結(jié)合層析成像數(shù)學(xué)理論Radon反變換,從定解問題推導(dǎo)了全息測量敏感場函數(shù)表達(dá)式。其次,將有限元仿真計算得到的全息測量敏感場應(yīng)用于模擬流動試驗(yàn)和全息成像。結(jié)果表明,基于復(fù)電位φ關(guān)于極徑r的偏導(dǎo)數(shù)的全息測量敏感場契合了Radon反變換的數(shù)學(xué)表達(dá),且充分體現(xiàn)了幅度、相位測量敏感性;反演所得流動圖像更加吻合實(shí)際流型。全息測量敏感場構(gòu)建有效克服了傳統(tǒng)單模敏感場在計算精度和計算效率等方面的局限性。
[Abstract]:The holographic measurement sensitive field obtained by finite element simulation is applied to analog flow test and holographic imaging . The results show that the holographic measurement sensitive field based on the partial derivative of the complex potential 蠁 with respect to the pole diameter r is applied to the simulated flow test and the holographic imaging . The results show that the holographic measurement sensitive field based on the partial derivative of the complex potential 蠁 has more coincidence with the actual flow pattern . The holographic measurement sensitive field construction effectively overcomes the limitation of the traditional single mode sensitive field in calculation precision and calculation efficiency .
