LOL so we both chose 100n then :-)
Well, I have lots to test, have you any clear EVP by this method?
Yes, that value works well to reduce some of the low frequency components. I did post just a fraction of my results using the optical flame microphone on this site. Just use the search function to find the examples using the terms 'optical microphone'.
There are countless ways to utilize light in experiments. Think of light or even heat as a carrier wave. Think of the frequency of the carrier as a specific wavelength or color . A red laser pen for example has a narrow bandwidth and specific frequency (vibration). White light has a wide bandwidth. A simple TV remote control outputs a specific frequency of IR light. The IR light is pulsed (modulated) at a specific rate to perform a function depending on the key that is pressed.
Have fun,
