Special Issue Information

Dear Colleagues,

Optics and photonics are among the key technologies of our time and offer the potential for novel applications in areas as diverse as optical measurement, sensing and analytics, monitoring, biomedical imaging, and diagnostics, as well as communication technology, to name some of the most prominent ones. These applications demand a high degree of control over the light fields and benefit significantly from concepts based on micro- and nanooptics and integration technology. The new capabilities lead to novel optical systems with enhanced functionality and unprecedented sensitivity and specificity, which are attractive for a wide range of applications previously not accessible. This Special Issue aims to provide an overview of some of the most recent development and exciting application areas in optics and photonics, indicating the broad multifaceted potential for the future. Articles covering novel optical concepts and systems as well as insights achieved in applications are invited.

Individual topics of interest include but are not limited to:

  • Integrated micro- and nano-optic concepts and devices
  • Wearable optics
  • Printed optics
  • Biosensors 
  • Surface plasmon resonance sensors
  • Optofluidic measurement
  • Distributed sensing
  • Fiber optic systems and sensing
  • Optical analytics, metrology, and spectroscopy
  • Medical diagnostics, imaging, and monitoring
  • Optical communication systems and technology

To accurately detect and monitor the internal temperature of an operating power transformer, the distributed optical fiber sensor (DOFS) was creatively applied inside an oil-immersed 35 kV transformer through high integration with the winding wire. On the former basis, the power transformer prototype with a completely global internal temperature sensing capability was successfully developed and it was also qualified for power grid operation through the ex-factory type tests. The internal spatially continuous temperature distribution of the operating transformer was then revealed through a heat-run test and the numerical simulation was also applied for further analysis. Hotspots of windings were continuously located and monitored (emerging at about 89%/90% height of low/high voltage winding), which were furtherly compared with the IEC calculation results. This new nondestructive internal sensing method shows a broad application prospect in the electrical equipment field. Also, the revelation of transformer internal distributed temperature can offer a solid reference for both researchers and field operation staff. Full article
