• Researchers Develop Material Capable of Being Transparent or Reflective in IR Spectrum

  Modern optical devices require constant tuning of their light interaction settings. Lenses need to change focus, lidars have to emit and receive light at different angles. For that purpose, there exist various mechanical apparatuses that shift lenses, rotate reflectors, and move emitters. But what if they all were to become unnecessary? An international research team that includes staff members of ITMO University and the University of Exeter have proposed a new metamaterial capable of changing its optical properties without any mechanical input. This development could result in a significant improvement in the reliability of complex optical devices while making them cheaper to manufacture. The study was featured on the cover of the May 2020 issue of Optica.

• ITMO Scientists Improve Lensless Computational Microscopy Technology

  Scientists from ITMO University and the Tampere University of Technology have improved upon a method for computational processing of optical signals in lensless microscopes. The algorithms they developed have helped increase the resolution of images acquired from such microscopes. Results of their research have been published in The Optical Society’s (OSA) scientific journal Optica.
