Technique to see objects hidden around the corner.

This is a new technique in feild of science. It will help to detect and identifu=y the hidden objects around the corners. It uses a laser which strickes on the adjacent wall and reflects back to hit the object and again reflects backs from objects and after some further reflections reaches some of the scattered laser light. A special camera detects the time difference between all the scattered reflected particles and accordingly sends data to the computer. The computers algorithm retreives the data and constructs a 3-D image of object.
Here's a video, this will wxplain you everything.

 Thank you.
