In contrast to line sensors, image area sensors have a matrix with pixels, i.e. an x- and a y-axis. The area sensor offers a high dynamic range and a fill factor of almost 100%. These sensors are very suitable for high-resolution camera systems in industry and science, where a special focus is placed on maintenance-free and wear-free systems. In addition, due to their high quality, surface sensors are used in the areas of document digitization and capture, measurements and inspections, medicine and research as well as for 3D vision.
A considerable advantage of area sensors compared to line sensors is that the image sensor area can be exposed simultaneously and without delay, without the need to add up individual segments. The overall result is output immediately. This enables very quick and gentle digitization, as the templates are only exposed to external environmental influences, such as incidence of light, for a short time. The scanning time for high-quality area sensors is approx. 0.3 seconds, which leads to enormous productivity, especially for large digitization projects.
At book2net, we only use area sensors for all of our scanning systems, as they combine all the advantages for our customers and the areas of application required: high depth of field, short scanning and processing times, high image quality and the option of live video preview. The latter is particularly helpful when positioning the originals on the scanning surface. With the help of the preview image and our Live Control Professional software module, users receive a finished result proposal before the scan is actually triggered. If needed, frames can be set within the live image, the quality can be checked and the orientation selected. This avoids incorrect scans and further optimizes productivity.
