Hi! I need some help with a circuit for a photoresistor.
I need to measure the distance to a light source ( 50 cm) with a photoresistor. I need to use an OP amp and i have to calibrate the circuit ,
so the surrounding light is 0V. Thanks!

I think photoresistor is not enough "intelligent” to tell you about the distance to the object. It can give you information related to the average light to which t is exposed, without details such as where the light is reflected off.
And details is what you need ....
