A half‐century of electronic imaging technology has begun to match and even surpass the performance of the eye, an amazingly sophisticated photon detector perfected by evolution.
The high sensitivity and efficiency of silver halide film can be traced to mesoscopic metal clusters—small groups of silver atoms subject to quantum size effects and the influence of their immediate environment.
Knowledge of the production, measurement and perception of color stimuli is essential for analyzing and optimizing complex photographic and electronic color‐imaging systems.
In microscopes based on this principle a defocused image disappears instead of blurring, allowing the user to independently image different layers of transparent materials.
Space‐based and aerial images can provide information about Earth resources, agricultural conditions, weather patterns and a host of other phenomena that would be impossible to observe from the ground.
