Several retinal prosthetic devices have been under development, but their optical resolution has been poor and they present challenges in achieving long-term compatibility with host tissue, Mr. Isacoff says.

Exclusive to Sony, 'By Pixel Super Resolution' processing further extends the camera's 5x optical zoom range, allowing full-resolution 16.2 megapixel images with a maximum 10x zoom.
It is the world's most powerful optical sensor, achieving up to 6400 dpi resolution without sacrificing the natural tracking feel of an optical sensor or yielding the robotic sensation of a comparable laser option.

First up, we'll cover the technical details -- the optical display projects a WQVGA resolution screen with 16 degrees of view.

Sequential optical images of high spatial resolution were used for the first time to derive surface ice velocities of Glaciar Upsala, a fast-moving fresh-water calving glacier in southern Patagonia.
Sharp, Clear 20x Lens: The FinePix F800EXR camera uses the FUJINON 20x Super Wide-Angle optical zoom lens that produces crisp high resolution results throughout the focal range, from 25mm wide-angle to 500mm telephoto, along with a Super Macro Mode that allow sharp focusing down to 5cm delivering the most brilliant detail possible.

Journal pages are scanned in at high resolution, and the text is extracted using optical character-recognition software.
However, as the size of content grows with higher resolution there is still a role for local storage technologies, such as optical discs, at least for some time in the future.
FORBES: What is the Future of Optical Disc Technology and who will Use It?
Further optimizing the quality, images are scanned at up to 600 optical dpi for resulting scans that have a crisp and clear 3800x7200 24-bit color depth resolution.

That would give it a resolution of a few thousandths of an arc-second enough, were this an optical rather than a radio telescope, to see a boulder just a few metres across on the surface of the moon.
The Coolpix 4800 has a resolution of "only" four megapixels, but they do toss in an 8.3x optical zoom lens (it's actually the smallest digital camera with that much optical zoom), which is nice since once most consumers realize they don't need more than four or five megapixels stuff like optical zoom and lens quality is going to be become a bigger and bigger deal.
