OPTICAL SCANNING Meaning and
Definition
-
Optical scanning refers to the process of capturing and converting printed or handwritten text, images, or other visual data into a digital format using light-sensitive equipment. It involves the use of optical devices, such as scanners or cameras, that employ sensors to detect and translate light reflections or patterns from physical objects or documents. The captured optical data is then converted into binary codes or digital signals, enabling computer systems to process, store, manipulate, and analyze the information.
Optical scanning technology employs various methods to convert physical data into a digital format. These methods include the use of flatbed scanners, where the object or document is placed on a glass surface and scanned by an optical sensor, or automatic document feeders, which sequentially scan multiple pages using a calibrated mechanism.
One common application of optical scanning is optical character recognition (OCR). OCR software analyzes scanned text and attempts to recognize the characters to convert them into editable and searchable digital text. This enables users to easily edit, search, and index large volumes of text-based documents.
Furthermore, optical scanning has extensive applications in areas such as archiving, data entry, digital imaging, barcode reading, and quality control. It is utilized across various industries, including healthcare, finance, publishing, logistics, and education, to streamline processes, improve productivity, and enhance data accuracy. The digital format obtained through optical scanning allows for easy storage, retrieval, and sharing of information, reducing the reliance on physical documents and enabling more efficient document management systems.

Etymology of OPTICAL SCANNING
The word "optical" comes from the Greek word "optikos", meaning "relating to sight" or "relating to vision". It is derived from the Greek word "opsis", meaning "sight" or "view".
The word "scanning" comes from the Old Norse word "skanna", meaning "to examine" or "to study". It is believed to be related to the Middle Dutch word "scennen", meaning "to look out" or "to descry".
When these two words are combined to form "optical scanning", it refers to the process of using light or vision to examine or study something, often used to describe the technology of digitally capturing or reading information from a physical document or image using light-sensitive devices such as cameras or scanners.
