What Is Scanner?
A Scanner Is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text scanning “wands” to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.
What Are Types Of Scanners Are available?
Modern scanners come in handheld, feed-in and flatbed types and are for scanning black-and-white only or color:
- Flatbed scanners are the most common type of scanner. They are called “flatbed” because the document is placed on a flat surface for scanning. Flatbed scanners can scan documents of various sizes and are generally more versatile than sheetfed scanners.
- Sheetfed scanners are designed to scan documents fed into the scanner one at a time. Scanners with automatic document feeders are smaller and more portable than flatbed scanners and are often used in home offices or small businesses.
- Handheld scanners are portable scanners that are smaller than flatbed scanners. They are designed for scanning documents on the go, such as newspaper articles or printed photos.
- 3D scanners are a bit different than traditional scanners in that they collect distance point measurements from a real-world object and translate them into a virtual 3D object.
How Does Scanner Work?
Scanners work by converting the image on the document into digital information that can be stored on a computer through optical character recognition (OCR). This process is done by a scanning head, which uses one or more sensors to capture the image as light or electrical charges.
The document scanner moves either the physical document or the scanning head, depending on the type of scanner. Then, the scanner processes the scanned image and produces a digital image that can be stored on a computer.
Scanners usually attach to a computer system and come with scanning software applications that let you resize and otherwise modify a captured image.
