For a university purpose I am preparing a project, actually I am thinking of using a photodiode in reverse bias in order to measure intensity of light.
I divided this project in some phases:
1) Current-voltage converter as current of diode is very small I convert it to voltage
2) Noise filter , in this case, how can I determine which frequencies I should eliminate and how? Consider that I am not very good at this, is it even possible to eliminate noise produced by photodiode itself?
3) Amplification of signal
Can anyone help me to understand how to do second step?
