Test Results Summary

The current test results show the progress that was made during this phase. The Electro-to-Optical Response Curves for the 850 and 1550 photodiodes were recorded. The transient response of the laser and photodiode system was analyzed. The IR sensor was tested. The accuracy of the analog read function on the Arduino was tested.
