Eye examination for visual acuity. Visual acuity is a measure of the spatial resolution of the visual processing system. VA, as it is sometimes referred to by optical professionals, is tested by requiring the person whose vision is being tested to identify so-called optotypes – stylized letters, Landolt rings, pediatric symbols, symbols for the illiterate, standardized Cyrillic letters in ...
Vision systems for inner spaces, as most industrial ones, contain an illumination system and may be placed in a controlled environment.

This is different from visual acuity, which refers to how clearly a ...
A3 Digital Mapping System consists of a digital airborne camera and an automatic ground processing system [1] produced by VisionMap. The A3 camera captures imagery using a sweep mechanism, which collects high resolution vertical and oblique imagery simultaneously. The captured data is post-processed by the A3 LightSpeed ground processing system ...
