Cover Story

Since its first application to retinal imaging nearly a decade ago, adaptive optics has helped researchers make fundamental advances in the understanding of how the human visual system works. more>>

Features

Adaptation and Visual Experience

Visual perception is regulated by processes of adaptation that adjust visual coding to match the scenes we see. Adaptation strongly influences subjective judgments about image quality and perceptual norms and may help determine what we notice when we look around us. more>>


Random Lasers: Development, Features and Applications

The random laser differs from other types of laser in that its cavity is formed not by mirrors but by multiple scattering in a disordered gain medium. The unique characteristics of the technology have encouraged scientists to explore new applications. more>>


Breath Diagnostics Using Laser Spectroscopy

Laser-assisted analytical instrumentation for biomedical diagnostics, in particular for the analysis of exhaled breath, is attracting increasing attention among researchers. The characteristics of laser spectroscopic techniques for breath monitoring are discussed and potential applications are outlined. more>>
