So it only works if the actor is wearing a smart watch or a heart rate monitor? That the laser only reads the device the actor has on his person?
Better use would be for those wearing a ankle monitor.

Bouncing a laser off a window pane to record voices has been around for some time.
This is new and improved!
Bounce a laser off a body and record the heart rate, also the minute variations of the heartbeat.
