Project Title Underwater Optical Communication Practical Testbed: Build, Measurement, and Performance Characterization
Project Description This project is a hands-on experimental testbed for underwater optical communication. The student will build an end-to-end optical link using an LED or laser diode transmitter and a photodiode-based receiver, and then perform systematic measurements to characterize link performance in water. The emphasis is on practical implementation, instrumentation, repeatable testing, and data-driven analysis rather than only simulation.

Experiments will be carried out in a controlled setup such as a water tank/aquarium. The student will measure received signal strength and bit-error-rate under different conditions including distance, alignment, modulation rate, ambient light, and water clarity (turbidity). The outcome will be a working demonstrator plus a complete measurement dataset and performance plots.

Expected Outcomes
• A working underwater optical communication testbed demonstrator
• A measurement methodology (test plan, calibration steps, repeatability checks)
• A performance dataset with plots and conclusions (range limits, optimal rate, robustness to turbidity/alignment)
• Documented hardware design, software, and recommendations for improving the link
Project Discipline Electrical Engineering, Electronics and Communication Engineering, Instrumentation, Engineering Physics, or Computer Science students interested in hands-on hardware and measurements.
