摘要:

采用基于光学涡旋日冕仪(OVC)的高对比度成像技术,对飞秒激光脉冲产生的空气等离子体引起的空间相位分布进行了测量。的OVC方法的灵敏度显着超过线全息和直接成像方法的基础上的空气等离子体荧光。0.046波的估计相位灵敏度为OVC在生物成像、材料表征以及等离子体诊断等领域的应用提供了机会。

英文摘要:

A high contrast imaging technique based on an optical vortex coronagraph (OVC) is used to measure the spatial phase profile induced by an air plasma generated by a femtosecond laser pulse. The sensitivity of the OVC method significantly surpassed both in-line holographic and direct imaging methods based on air plasma fluorescence. The estimated phase sensitivity of 0.046 waves provides opportunities for OVC applications in areas such as bioimaging, material characterization, as well as plasma diagnostics.
