  • Publication number: 20250137850
    Abstract: A pair of light rays spatially-sheared with a controllable beam-shear distance is generated by a module having a beamsplitter (BS) and two mirrors. The BS splits an input light ray into first and second split light rays respectively propagated on first and second light paths. The two mirrors are respectively located at distal ends of the two light paths, and cause each split light ray to undergo a two-stage reflection, thereby generating first and second reflected light rays directed to the BS. The BS processes the two reflected light rays to generate the pair of spatially-sheared light rays. Orientations of the two mirrors in yaw angle, pitch angle, or both, are jointly adjustable to realize and control the beam-shear distance without using any birefringent crystal-based prism. The module is used to form differential interference contrast (DIC) microscopes providing variable shear distances, advantages of orientation independence, etc.
