OPN Image of the Week

A laser striking a periodic pattern diffracts in striking fashion. The pattern that appears here is due to the nature of arrangement of the micromirrors. The array acts as diffraction gratings. Several orders can be seen with varying intensities. Taken by Gerald John Doblado of the Structured Light Group, this photo was published as Image of the Week in Optics & Photonics News by The Optical Society (OSA) on 08 February 2016.
