When I tested the prototype, as I already expected, it was impossible to maintain a stable communication via I2C when the rotor turns around. 

The positive part is that the power via "SD pins" was stable with some capacitors, maybe using a couple more of SD pins gets a more stable voltage.

Great work! I would suggest optocoupling to transfer the ToF data with small microcontrollers (like 10f2xx or atTiny), only delivering power through the slip ring. Something similar can be found in the orange xiaomi lidars.

Why I2C communication fails ?
