摘要：
A novel technique for obtaining differential images with a scanning microscope by using a two-mode optical fiber is proposed. It is shown that both the differential amplitude and the differential phase images can be obtained by adjusting the differential phase delay between the fiber modes. The technique is demonstrated experimentally, and differential images of a specimen consisting of sharp edges in both amplitude and phase reflectivity are presented.
