Abstract:
In a world increasingly reliant on speedy, wireless data communication, research into new mediums
for faster and more reliable data transfer is imperative. As conventional radio-based communication
networks are phased out, optical wireless communication (OWC) holds great promise due to its speed,
security, and spectral broadness. One particular area of scientific interest is the implementation of
OWC in astronautic communications. The goal of this research is to demonstrate the use of visible
light communication (VLC) in aerospace communication and information transfer. Researchers created
a robot-camera prototype activation system to model a potential application of laser light in these
areas. This prototype system enables laser light to activate a robot’s movement, as well as the
capturing and recording functionality on the camera device. After the system records an image or
video, a researcher-built Raspberry Pi-based system can wirelessly transmit the data as laser light.
The laser light can then be subsequently decoded back into the transmitted data by the second half of
this system. Researchers evaluated the prototype circuit's voltage and current at two transistors to
study the effects of the photoresistor's varying resistance under different light conditions. The data
collected reflected the amplifying effects of the transistors to control the relay. The prototype
demonstrates the prospects optical wireless communication has in astronautic communications,
robotics, and research.
