Electro-optical propagation effects
conference paper
Electro-optical sensors detect the radiation emitted and/or reflected by objects. Outside the laboratory, where the distance between sensor and object may become large, the intervening atmosphere interacts with the radiation while it propagates to the sensor. The major propagation effects are (1) macroscopic refraction effects, (2) turbulence (or microscopic refraction effects), and (3) transmission losses. Propagation effects cause image distortions and a loss of contrast and thereby affect military relevant products such as detection and classification distance. This paper provides an overview of the major propagation effects and their relation to the environmental conditions, and discusses a few recent advantages.
