OPT8241: Multiple ToF cameras interference problem

Change the frequency of the modulation demodulation of the cameras. This works great according to www.slideshare.net/.../multicamera-timeofflight-systems-siggraph-2016
and according to my own experiments.

Moetaz's suggestion is good. Change the frequencies of they are not the same. Typically 100KHz to 200KHz separation can get you 40dB of crosstalk suppression. See Robert Lange, “3D time-of-flight distance measurement with custom solid-state image sensor in CMOS/CCD technology”
