bessel beam

基本解釋

It is proved by theoretically analysis and numerical calculations, that low rank Bessel beam is stable in the multiple pass ring resonator.
理論分析和迭代法數(shù)值計算表明，低階貝塞爾光束是適合多程環(huán)形腔的穩(wěn)定模式；
Under appropriate conditions a [Bessel beam] can act as an ‘optical tractor beam,’” write physicist Jun Chen of Fudan University in Shanghai and colleagues.
在合適的條件下，貝塞爾光束可以作為一種光學(xué)牽引束?！?復(fù)旦大學(xué)物理學(xué)家陳?。↗un Chen,音譯）和他的同事們在文章中寫到。
Results show that if the cross-section of the axicon is ideally manufactured in circular symmetry, the field distribution behind the axicon is approximately an ideal Bessel beam.
計算結(jié)果指出，當(dāng)軸棱錐的截面為圓對稱的理想加工時，軸棱錐產(chǎn)生的光場分布為近似理想的零階貝塞耳光。
