The prototype uses an ultra-short high-intensity burst of laser light to illuminate a scene.
The light particles scatter and reflect off all surfaces including the walls and the floor.
If there is a corner, some of the light will be reflected around it. It will then continue to bounce around the scene, reflecting off objects - or people - hidden around the bend.
Some of these particles will again be reflected back around the corner to the camera's sensor.
Are you thinking what I'm thinking? Yes -- no more Mrs. Doubtfiring it into the women's locker room! I can finally film from the safety of pretending to drink at the water fountain! Uh-oh, here comes a suspicious gym employee. Stay calm and act cool. GAAAAH I HAVE DIARRHEA I'M REALLY DEHYDRATED! God I'm smooth.

Thanks to Rev Dr Dom, who can already see around corners and up women's dresses because he taped a mirror to the end of his walking stick. Stay classy!
