Development and experimental validation of a Python-Based Library for predicting received output current in LED-Photodiode configurations

• Typ der Arbeit: Forschungsprojekt
• Status der Arbeit: abgeschlossen
• Betreuer: Marek Jahnke

In an LED-Photodiode-setup an LED sends out light that is received by a photodiode, which converts the received light power to a current. This transmission depends on many factors, including the component properties, as well as the distance and angle of the two components in front of each other.

In this project work, the fundamental calculations from LED to a Photodiode and its current output are to be researched first. A simple Python-based Library should be developed, that can calculate the light power transmission and the current output at the photodiode, depending on the used components and the setup. Different LEDs and photodiode components should be added to the Library based on datasheets. The calculations should take into account component properties, angle, distance and other influences.

At the end, the calculations should be compared with real measurements to get an impression of correctness. The measurements may be used to tune the formulas if necessary.
