Abstract
Future deep-space exploration missions demand a
broadband and integrated communication infrastructure to
transport the scientific data to Earth. Optical communication
employing optical arrays receiver is a viable alternative to the
current NASA deep-space RF-based network. Atmospheric
turbulence is a major limiting factor for the inter-planetary
optical links. Investigation of the use of adaptive optics
subsystems is carried out for the compensation of coupled effects
of optical turbulence and background noise, in direct detection
optical array receivers. The simulation and analysis of an end-toend
deep-space optical communication link between a spacecraft
in Mars orbit and Earth-based telescope array receivers show
that the incorporation of adaptive optics systems results in
considerable performance improvement in achievable data rates.
