Call for
The use of sensors for active and passive remote sensing of the Earth, its atmosphere and the oceans, for free-space laser communications, and for high-resolution imaging of ground-based, immersed and airborne objects are fields of growing interest for both civilian and military applications.

Such high-resolution optical sensing systems use spectral regions varying from UV to Radar. However, they all must deal with detrimental environmental influences, be it over km-long ranges in the atmosphere or even over only several meters when light propagates through very turbid media such as ocean water. Instrument and measurement analysis therefore depends crucially on a thorough understanding of all optical effects that limit the sensor performance operating in an absorbing, scattering, and radiating random medium. Increasingly important in this area are modern methods used to ameliorate these effects through compensative hardware, algorithms, and measurements of environmental parameters performed at various locations around the World. Contributions are invited on the following topics and those related to them:

  • Characterization of the Propagation Environment:
  • profiles of temperature, humidity, extinction, refractivity, radiance (also non-LTE), optical turbulence; updates of transmission and radiance codes, atmospheric refraction, atmospheric turbulence, VIS and IR backgrounds, statistics of propagation parameters; measurements of scattering and turbulence underwater.

  • Propagation and Imaging through Optical Turbulence:
  • meteorological models, the strong turbulence regime, laser beam propagation, laser speckle effects; correction methods for atmospheric effects in remote sensing, compensation for anisoplanatism and scintillation.

  • Propagation and Imaging through Inhomogeneous and Dense Media:
  • laser beam propagation, scattering and multiple scattering effects, aero-optic and jet plume effects; correction methods for atmospheric effects; coherent and incoherent imaging in anisoplanatic conditions; laser beam projection on an extended target; double-pass propagation and target-in-the-loop compensation of atmospheric turbulence.

  • Laser-based Sensing and Laser Communications:
  • laser beam focusing, sensing, and free-space communications, system and atmospheric simulations, hardware configurations, communications theory issues, bandwidth limits, multiplexing issues, adaptive optics use for increased performance, loss of coherence for active (laser) systems.

  • Techniques for Mitigation of Atmospheric Effects:
  • adaptive optics, deconvolution, “lucky imaging”, global and local image stabilization and de-warping, sensor fusion, image post-processing

  • New Devices for Atmospheric Measurement or Compensation:
  • novel optical components such as liquid crystal and MEMS devices, wavefront sensors, high-frame rate and low-noise IR detectors.
