This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We are developing a fiber optic probe-based dual-beam interferometer for measuring subnanometer displacements of surfaces without need for a separate reference surface. In the new probe design the reference reflection is provided by a zero-degree cleaved fiber end and the transmitted beam is focused by a gradient-index lens. The fiber probe will have applications in biology and engineering.

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。我们正在开发一种基于光纤探头的双光束干涉仪，用于测量表面的亚纳米位移，而不需要单独的参考面。在新的探头设计中，参考反射由零度分裂光纤端提供，透射光由梯度折射率透镜聚焦。这种光纤探头将在生物学和工程学中得到应用。
