How does a line scanner work?
Line scan technology involves building up an image, one line at a time, using a line sensor (linear array), which passes in a linear motion over an object, or where the object passes in a linear motion under the sensor.
What is a line scanner?
Simply put, a line scan camera is a strip that captures one row of pixels at a time in quick succession, while either the camera is moved over an object, or the object is moved under the camera.
What is the difference between line scanning and area scanning?
Area scan cameras provide a fixed resolution, allowing for simplified installation where moving cameras or objects are not desired or practical. Area scan cameras can image a defined area quickly, whereas a line scan camera must be moved over the area to produce a similar image.
