Next-Generation Cell Phone Cameras

Tim Hayes

The mobile camera market is being driven by consumers’ desire for big imaging capability in smaller and smaller packages. Despite the limitations imposed by these competing demands—or perhaps because of them—many companies are unleashing creative solutions that incorporate wafer-level optics, liquid lenses and LED flashes.

Recycled Fiber Optics: How Old Ideas Drove New Technology

When it comes to fiber optics, everything old is new again. Crucial building blocks of modern technology were once written off as impractical, including single-mode fiber and wavelength-division multiplexing. Now coherent communication systems, abandoned in the 1980s, have become cutting-edge high-performance systems.

High-Performance Sensing Using Fiber Lasers

Fiber laser sensors are capable of achieving fundamentally limited strain resolution. Their high sensitivity per unit length enables new sensing possibilities, miniaturization of existing sensors and simplification of sensing mechanisms.
