OPN Image of the Week
OPN Image of the Week [February 8, 2016] 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. —Gerald John H. Doblado, National Institute of Physics, University of the Philippines Diliman
