It's not resolution. Nor is it size of the screen or price of the TV. It's the contrast ratio that makes all the difference in picture quality between two otherwise identical TV sets. This might seem ...

A method that boosts the contrast of high-resolution optical images has the potential to enable lithography at the nanoscale. A method that boosts the contrast of high-resolution optical images has ...

An innovative combination of existing technologies shows promise for noninvasive, high-resolution imaging of cartilage in research on the progression and treatment of the common degenerative disease ...

Although electron microscopy can already reveal details as small as one nanometer, ongoing research seeks to break through barriers limiting image quality and reducing the optical dose on the samples.

An insect's compound eye has superior visual characteristics such as wide viewing angle, high motion sensitivity, and large depth of field while maintaining a small volume of visual structure with a ...

The CNTX contrast sensor is billed as the highest-resolution white LED contrast sensor on the market, and the only sensor able to reliably detect up to 50 gray-scale levels. Unlike standard contrast ...

We show you how these important parameters affect the appearance of your photos. This article is a follow-up to the one on reading lens manufacturers’ Modulation Transfer Function (MTF) graphs. We ...

Image transformation Brain scan slices acquired with a portable, low-field Hyperfine MRI scanner (top row) and corresponding slices output by the LF-SynthSR algorithm (bottom row). The Hyperfine scan ...
