In this work, a free-space infrared communications system is described. The system has the capability of using
previously captured scintillation data and introducing the effects onto the bench-top system. This effectively acts as
a scintillation simulator which emulates an optical link that is effected by the weather and various physical
conditions at the time of transmission. The method used for scintillation simulation is described. The transmission
method of the system is a hybrid combination of traditional frequency modulation (FM) and optical amplitude
modulation (OAM) combined with Multiple Quantum Well (MQW) Modulating Retroreflector (MRR) technology.
The result has produced a robust, low power system that is capable of transmitting real-time audio information with
high clarity along a channel that accurately simulates the atmospheric effects of scintillation. The system is capable
of transmitting along a link of several kilometers, depending specifically on the characteristics of the interrogator
and sensor components chosen for the system.
