Hello everyone!
I'm new to this forum and I'm excited to be here!.
I currently working on to make a self-mixing laser diode vibrometer to measure sound from a loudspeaker.
I've a schematic over a setup but I have some questions about it.
1. Where should I make the output measurements from the schematic? my guess is between photodiode and plus?.
2. Can I just record the output from the setup into an audio interface to record the sounds? or do I need to de-modulate the signal somehow?
Best!
