Tiny Camera Takes a Wide View

Facebook X LinkedIn Email
SAN DIEGO, Oct. 2, 2013 — A new imager achieves the optical performance of a traditional wide-angle or fish-eye lens — and in high resolution — but in a device less than one-tenth the volume. Such a system could enable high-resolution imaging in unmanned aerial microvehicles, or smartphone photos more comparable to those from a full-size single-lens reflex (SLR) camera, its developers say. Researchers at the University of California, San Diego, created the imager, which has a 100X range of focus — meaning it can image anything between half a meter and 500 m away — and 0.2-mrad resolution,...Read full article

    optical fiber
    Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a medium for conveying information in the form of light pulses, typically in the realm of telecommunications, networking, and data transmission. The core of an optical fiber is the central region through which light travels. It is surrounded by a cladding layer that has a lower refractive index than...
