RealSense D400 - Strobing IR Projection

[CWest4]

Is it possible to strobe the IR projection synchronously with the IR camera capture? The purpose of this is a scenario where there is a secondary sensor that measures in the IR spectrum. The IR projection from the RealSense would interfere with this sensor. If the projection could be strobed, then the secondary sensor could be triggered out of phase with the depth measurements and IR projection.

Rather than strobing the projector (if it is even possible), it may be better to use the D435 camera model's ability to sync its stream with external sensors using the four GPIO pins it has on it.
