I am a noob in circuits
i want to detect minor changes in fiber optic sensor.
I use IRL81 as source and OP560A as Photo detector.
100HZ 50% duty cycle has used from arduino to fire the LED
[Lockin amplifier, phase detector, synchronous detector, voltage mixer, phase locked loop are confusing me]
In my application what i have to use?
