 Laser Reconstruction: 6 targets, 5 mirrors (Posted on 2007-12-14)
Two lasers enter a limitless space in which there are 6 targets.
One laser enters vertically downward while the other is initially horizontal from the right.

You have 5 mirrors, each of which can deflect a beam at either 45° or 135°.

Each laser beam passes through all targets only once.
Each segment of one laser beam passes exactly through 1, 2 and 3 targets
while those of the other never pass through more than two.

You may care to challenge yourself by fitting all targets into a 4 x 4 grid.
As a further challenge fit the 6 targets into a 4 x 4 grid, use the same rules but use only 4 mirrors.

Note: 1. Brian Smith's Laser Puzzle was the inspiration for this.
2. I acknowledge Brian Smith's thoughts re the use of a 4 mirror version.
