I want to implement the circuit with LEDs and infrared diode and compare the output signal with the signal of my LRL. In this way, we could discriminate the gold given that there seems to be an affinity between infrared radiation and gold.

Yes my friend I know that. But I mean our colleagues Andres is Right to includes that in her system and he is have succes I like the mans and I believe to him. Again me correct I put for you Diagram and PCB distributed by him to understand the sytem how to work and I have advice you to use the Low frequency 1 H to 1000Hz not 10khz
By your way I think we have problem with our dear colleagues Andreas he is always misunderstanding me
maybe for my poorly English
Thanks and go to do it by your mode.
