Abstract
A structured-illumination module included in a 3D-structured-illumination-based fluorescence microscope, the structured-illumination module comprising: a structured-illumination-module frame; a beam-alignment module including a central tilt mirror coupled to an underside of a top horizontal plate of the structured-illumination-module frame; a set of directional mirrors, one of which receives, at a given point in time, input, polarized, coherent light reflected from the central tilt mirror; three sets of beam splitters, on three arms of the structured-illumination-module frame, the each splits an incident illumination beam, reflected to the set of beam splitters from a directional mirror of the set of directional mirrors, into a coherent beam triplet; and a phase-shift module that receives a beam triplet, at a given point in time, generated by one of the sets of beam splitters and reflected from the beam-alignment module and that introduces a desired relative phase relationship among the beams of the beam triplet.
