    • Blind Super-Resolution Approach for Exploiting Illumination Variety in Optical-Lattice Illumination Microscopy 

      Samanta, Krishnendu; Sarkar, Swagato; Acuña, Sebastian; Joseph, Joby; Ahluwalia, Balpreet Singh; Agarwal, Krishna (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-19)
      Optical-lattice illumination patterns help in pushing high spatial frequency components of the sample into the optical transfer function of a collection microscope. However, exploiting these high-frequency components require precise knowledge of illumination if reconstruction approaches similar to structured illumination microscopy are employed. Here, we present an alternate blind reconstruction ...

    • Transmission structured illumination microscopy with tunable frequency illumination using tilt mirror assembly 

      Samanta, Krishnendu; Ahmad, Azeem; Tinguely, Jean-Claude; Ahluwalia, Balpreet Singh; Joseph, Joby (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-26)
      We present experimental demonstration of tilt-mirror assisted transmission structured illumination microscopy (tSIM) that offers a large field of view super resolution imaging. An assembly of custom-designed tilt-mirrors are employed as the illumination module where the sample is excited with the interference of two beams reflected from the opposite pair of mirror facets. Tunable frequency structured ...
