Alternatively, we can image that the incoming wave is diffracted by the object and the resulting diffracted wave is then diffracted again by the objective lens . 換一種方式,我們可以這樣想象:入射波被物體反射,所得到的衍射波再一次受到物鏡的衍射。
On the basis of the study of the characteristics of diffracted wave produced during the vibration propagation along the fissures , in association with practical example , the paper introduces the features of prospecting the depth of fissures of structural mass by using the seismic method 該文在研究振動(dòng)沿裂縫傳播時(shí)所產(chǎn)生繞射波的特征基礎(chǔ)上,結(jié)合實(shí)例,介紹了運(yùn)用地震法探測(cè)結(jié)構(gòu)體裂縫深度的方法特點(diǎn)。
Abstract : on the basis of the study of the characteristics of diffracted wave produced during the vibration propagation along the fissures , in association with practical example , the paper introduces the features of prospecting the depth of fissures of structural mass by using the seismic method 文摘:該文在研究振動(dòng)沿裂縫傳播時(shí)所產(chǎn)生繞射波的特征基礎(chǔ)上,結(jié)合實(shí)例,介紹了運(yùn)用地震法探測(cè)結(jié)構(gòu)體裂縫深度的方法特點(diǎn)。
The holographic wavefront recording process records the interference pattern of the object and the reference waves , and thus forms the hologram , which simultaneously records the information about the amplitude and phase of the object waves ; the holographic wavefront reconstruction , by means of the diffracted waves , can reconstruct the original object wave from the hologram illuminated by lights 全息波陣面記錄將物光和參考光以干涉條紋記錄成全息圖,此全息圖同時(shí)記錄了物光波的振幅和相位;全息波陣面重現(xiàn),就是用光波照射全息圖,通過光的衍射,從全息圖中再現(xiàn)出原始物體的光波。
