Thank you for your detailed answer. I guess the square law relates to the fact that the output electrical power varies as the square of the input optical flux (output current is linear towards light flux). Still, I though that detector sensitivity is expressed as current vs light flux. So, can...
Dear all,
This is my first post and I'm not sure if it's the right place to ask so don't hesitate to advise if necessary.
I would like to know if it's possible that an optical detector (the complete system including sensor and front-end electronics) has a better sensitivity at medium flux than...
