Cover Story

In recent years, forensic science has been glamorized in prime-time television and movies. Beyond the special-effects magic, new optical technologies are making their way into the crime lab—as quickly as budgets and trial judges will allow. more>>


Welcome to the Wonderful World of 3D: Parallax Barrier Experiments Part IV

The first two installments in this four-part series explored the history and principles of 3D imaging, and the third included anaglyph experiments. This fourth and final article provides instructions for parallax barrier experiments. more>>

Non-Uniform Color Scales: The Artwork of Kristin Quinn

What is the color of amber? Iron ore? Pollen? How can wind and water be suggested? Kristin Quinn, daughter of former OSA Executive Director Jarus Quinn, explores such questions every day through her dynamic artwork. more>>

Surface Plasmon Polaritons on Metallic Surfaces

Recent advances in nano-fabrication have enabled a host of nano-photonic experiments involving subwavelength metallic structures. This activity has, in turn, reawakened interest in surface plasmon polaritons (SPPs). Here, numerical simulations are used to verify the detailed structure of long-range SPPs. more>>


Two-dimensional images can be delayed without destroying the information they carry—even at such low light levels that each pulse averages less than one photon. more>>
