Offset scanning is a technique used in various scanning technologies where the scanning head moves slightly from side to side while capturing an image. This movement helps to reduce the effects of artifacts and improve the overall quality of the scan by ensuring that each point on the scanned object is captured from multiple angles. Offset scanning is commonly used in document scanners and medical imaging devices.

What are the techniques in scanning?

Scanning techniques typically include various methods such as optical scanning, which uses devices like scanners to convert physical documents into digital formats; barcode scanning, which utilizes scanners to read barcodes for inventory and tracking; and network scanning, employed in cybersecurity to identify active devices and vulnerabilities within a network. Additionally, there are image scanning techniques, such as laser scanning and sonar scanning, used for creating detailed 3D models of objects or environments. Each technique serves specific purposes across different fields, from document management to security assessments.


Where scanning is used?

Scanning is used in various contexts, including document management, data entry, and security. In offices, it helps digitize paper documents for easier storage and retrieval. In retail, barcode scanning facilitates inventory management and checkout processes. Additionally, scanning technology is employed in security systems for identity verification and access control.


What is glass box scanning?

Glass box scanning, also known as white box scanning or static application security testing (SAST), is a method of scanning software where the tester has access to the source code and structural information of the application being tested. This allows for a thorough analysis of the code to identify security vulnerabilities such as coding errors and design flaws.


What is scanning in reading?

Scanning in reading is a technique where you quickly look through a text to find specific information, such as keywords or dates, without reading every word. It is an efficient way to locate details in a text without the need to read it in its entirety. Scanning is often used when you have a specific question or need to find particular information within a text quickly.
