    • Characterisation of Silicon (Si) fibre Bragg grating in near-infrared band for strain and temperature sensing 

      Theodosiou, Antreas; Kalli, Kyriacos; Hawkins, Thomas A.; Ballato, John; Fokine, Michael; Gibson, Ursula (Journal article; Peer reviewed, 2018)
      This letter describes fibre Bragg grating inscription in crystalline siliconcore fibre using visible light femtosecond laser pulses. The femtosecond pulses at 517 nm propagate through the transparent silica glass cladding ...

    • Fourier ptychography algorithm based on scaled Fourier transform 

      Hasanzade, Mojde; Hussain, Nazabat; Breiby, Dag Werner; Akram, Muhammad Nadeem (Peer reviewed; Journal article, 2021)
      This letter discusses an alternative Fourier ptychography algorithm based on the scaled fast Fourier transform propagation. The advantage of this scheme is that it enables a zoom-in capability of the object spectrum and ...

    • Improved resolution Fourier ptychography scheme using oil-filled dome-shaped LED array 

      Gholamimayani, Mahdieh; Hussain, Nazabat; Breiby, Dag Werner; Akram, Muhammad Nadeem (Peer reviewed; Journal article, 2022)
      Utilising angular-varied illumination in Fourier Ptychography, the resolution of optical microscopes can be increased and the phase of the sample can also be recovered while maintaining a wide field-of-view. In this work, ...
