Noise suppression in the signal spectral induced by atmospheric turbulence on the fso (free-space optical) communications
" Beam wander and spatial noise that are modulated on optical propagation produce noise modulation in the signal spectral before being received by a Photodetector (PD). In order to suppress noise modulation in the signal spectral, we present an Optical Spatial Filter (OSF) method that is composed of the cone reflector and a pinhole as a detection method. A cone reflector is designed to suppress beam wander in order to minimize temporal noise that fluctuates randomly ... "
