IMAGE OF THE WEEK

Engagement ring sparkle
Engagement ring sparkle

The sparkles from my wife’s engagement ring are visualized by a collimated supercontinuum laser incident normal to the largest diamond in the ring. A piece of paper is used to trace out the beam in this long exposure image. Small rainbow beams can be seen shooting away from the stone, proof that the dispersive design of the diamond is doing its job. [Second place winner, 2018 After Image photo contest.]
