In high-speed and high-resolution applications, line scan cameras outperform traditional area scan counterparts. But really the reason behind using a line scan camera is to take continuous, high res image thus acquiring details of moving objects. The cameras can deliver resolutions up to 8,000 pixels in a line and capture even the smallest detail accurately – an essential requirement for quality control systems on manufacturing lines.
In 2024 for example, linescan cameras were proven to outperform conventional multiple shutter and prism based camera by descern.data in the review by Vision Systems Design as they had been able to inspect production line at a speed up to 200.000 lps (lines per second) even so with dynamic environment.levels over traditional systems without confusion of either one or two bins being emptied and all images leaving though other products are not intended into output capture bin resting on different strand above same conveyor belt<>(); __); It is this high-speed that has made it possible for real-time defect detection and process monitoring, which allows to control what happens in industries like automotive or textiles where the production lines spin at rapid rates.
The next advantage includes the direct image capture of slender or larger continuous surfaces. When imaging large areas, it is common to stitch images together of the scanned part area by line scan cameras exposures these problems can be avoided. According to a study done by the International Journal of Imaging Systems and Technology on 2024, many line scan cameras do not even have shutters which means that it provides distortion free photograph continuously —very important for inspection items such as rolls of film or fabric.
Also contributing to their efficiency is the fact that line scan cameras require less data and processing. By recording images one line at a time, the camera produces smaller files than can be output from full frame cameras which lowers the amount of data storage and processing capability necessary. This has led to rapid data analysis and an overall reduction in system price making line scan cameras a cost-effective solution for many high-resolution imaging applications as well.This results, according to the 2024 technical report.
On top of that, line scan cameras have great depth-of-field and low distortion. This ability to image continuously means that the whole of your target will be in focus, independent on its position or surface roughness. This advantage is documented in a case study for the year 2024 from the International Society for Optics and Photonics regarding applications such as rail inspection (where detecting structural anomalies require constant focus).
In summary, line scan cameras are a useful tool for efficiency and high-resolution capabilities supporting reduced data processing needs; with broad use across several industries. Click here for more information and lineup of line scan camera models
