Greetings,
I hope I am posting in the correct forum, if not please forgive the newbie mistake.
Attached is a circuit used to detect a pulsed red laser 635 - 650nm. Could some one please explain the reasoning behind the use of the inductor. and what effects would it have if I changed the inductor to a higher value. The output signal is fed into an lm324 for appropriate signal amplification.
Currently the ambient light is filtered using an optical filter, would it be possible to implement an electronic filter for the said wavelengths without getting too complex.
The circuit works as it is, I am just trying to learn some of the basics. any possible suggestions to improvement of the circuit are extremely welcomed.
cheers
