The paper discusses a low power consumption, light weight and low cost 10MHz free-space optical communication
(FSO). The system is designed for mounting on mobile platforms, with effective range of at least 50 meters. Light-Emitting Diodes (LEDs) and Laser diodes (LDs) are used in the transmitter for comparison for their relative performance
in the system. The receiver features a beam splitter that feeds part of the data link optical signal to a quadrant
photodetector and controls a tracking/stabilization system using microcontroller. Since almost all commercial FSO
systems are mounted on fixed positions such as buildings, the paper explores the possibility and challenges of designing
a FSO system for a mobile system such as remotely operated-vehicles or between ships.
