How can I reproduce the wavefront interference photon detector seen on Nova?

I am looking for someone that can tell me how to reproduce this experiment sen on nova last week A rectangular black box was used with a low power ? 1mw red laser . A long box was used there were 2 vertical openings left and right of the laser path to the photon detector. There was no direct line of sight path to the photon detector. The wavefront that apparently preceded the laser's source of photons produced and third interference photon detection smear directly inline with the laser whose path was obstructed.

To reproduce this experiment, you will need a rectangular black box with two vertical openings on the left and right side of the laser path. You will also need a low power 1mw red laser and a photon detector. The laser should be pointed at the photon detector, while the wavefront should be positioned so that it precedes the laser's source of photons but is not in a direct line of sight path to the photon detector. Once everything is set up, you will need to observe the interference pattern produced by the wavefront on the photon detector.
