The word optics is derived from the Greek term τα ὀπτικά meaning 'appearance, look'. [1] Optics was significantly reformed by the developments in the medieval Islamic world, such as the beginnings of physical and physiological optics, and then significantly advanced in early modern Europe, where diffractive optics began. These earlier ...
Fournier d'Albe's Optophone and Tauschek's Reading Machine are developed as devices to help the blind read. [1] 1931–1954 First OCR tools are invented and applied in industry, able to interpret Morse code and read text out loud. The Intelligent Machines Research Corporation is the first company created to sell such tools. 1954–1974
They then installed two IBM 1232s in 1964. Being able to use a full 8 + 1 ⁄ 2 in × 11 in (22 cm × 28 cm) answer sheet rather than a 7 + 3 ⁄ 8 in × 3 + 1 ⁄ 4 in (18.7 cm × 8.3 cm) mark sense card, eliminated the need to use multiple answer cards per test per student, as well as dramatically increased the marking speed for test answers.

In 1821, he proposed a telegraphy system utilizing one wire per "galvanometer" to indicate each letter, and reported experimenting successfully with such a system. However, in 1824 , Peter Barlow reported its maximum distance was only 200 feet, and so was impractical.
[1] Optical engineering is the field of engineering encompassing the physical phenomena and technologies associated with the generation, transmission, manipulation, detection, and utilization of light. [2] Optical engineers use the science of optics to solve problems and to design and build devices that make light do something useful. [3]
An optical reader is a device that observes visual information and translates it into digital information, [1] as found within most image and barcode and matrix-code scanners. An example of optical readers are marksense systems for elections where voters mark their choice by filling a rectangle, circle, or oval, or by completing an arrow. After ...
