If I cross two beams of light will there be optical crosstalk? The beams will be crossing in air at 70° angle.
I have a sensor which will measure scattered light. There will be a sensing beam, and a feedback beam. The sensing beam will carry in the order of 1 uW (micro). The feedback beam will carry in the order of 10 mW (milli).
I’m thinking about crossing two of the beams, because space is at premium. There’s no fundamental reason for crossing them.
