Adaptive Optics for Biomedical Microscopy

Over the last decade, researchers have applied adaptive optics—a technology that was originally conceived for telescopes—to high-resolution microscopy in order to overcome the problems caused by specimen-induced aberrations.

Fishy Photons: Invisibility and Transformation Optics

As we see when looking at fish in an aquarium, optical materials can distort the actual locations of objects. Scientists are now able to manipulate light in “fishy” ways that may enable big scientific breakthroughs such as invisibility cloaking in the near future.

Why Peer Review Matters

The peer review of manuscripts submitted to OSA journals is a hugely important component of the scholarly communication process. In order for OSA publications to remain sustainable, everyone who submits a manuscript should complete at least two reviews. Are you doing your part?
