✧˚⋆ DEVLOG 1: Aside from (lots…) of documentation, I created this TIA photodiode circuit in Tinkercad to mirror the one which will measure the fringe shifts in my interferometer.

Safe to say, this was not all smooth sailing - the components were challenging to wire correctly (particularly the op-amp) and the range of output values was.. disheartening at times (512-513 or 0-2) but I finally got it to an amplified degree!

One of the solutions was simply flipping the polarity of the photodiode lol. It now outputs values from 0-1021 depending on the inverted light intensity, which is optimal for my project as the effect of real-world noise will now be much lesser than without the amplification system. I’ll keep you guys updated! Check out my github or ask me for more info :)
