Phase‐shifting differential interference contrast microscope with Savart shear prism and rotatable analyser

H.‐X. TRỊNH, S.‐T. LIN, Z.‐W. CHEN, T.‐H. LEE

Summary

A novel differential interference contrast microscope (DICM) is proposed in this research. It is constituted by inserting a Savart shear prism between the objective and sample of a polarising microscope having a rotatable analyser as the phase‐shifter, and it is with the ability to enhance image contrast using the principle of shearing interferometry. This letter is to introduce the configuration, interpret the interference patterns and present the experimental setup of the DICM. In addition, this letter is to display the experimental results from the uses of the setup; the results demonstrate the validity and ability of the DICM.
