High quality imaging systems such as Optical Character Recognition systems (OCR) harness the illumination from LED light sources to capture and to read the identifying markings on containers and inspect the containers for damage. Many of the OCR applications use line scan illumination technology to perform these tasks that manage the flow of shipping containers into and out of ports.<\/p>\n<h2>How Inspection Systems Work<\/h2>\n<p>Inspection systems at ports are used to read the uniquely recognizable identifying marks on the exterior of the shipping containers. The process starts when the containers are loaded on a truck or a rail carriage and moved through the system in a classic line scan like application.\u00a0<a href=\"https:\/\/www.prophotonix.com\/led-and-laser-products\/led-products\/led-line-lights\/\">LED line lights<\/a>\u00a0illuminate the containers for inspection as they pass through an automated terminal rail or gate system. The container is automatically identified and inspected for any damage which may have occurred during transport.<\/p>\n<h2>Environmental Considerations<\/h2>\n<p>External environmental conditions can provide a challenge for the illumination system:<\/p>\n<ul>\n<li><strong data-redactor-tag=\"strong\">Extreme Conditions<br \/>\n<\/strong>Temperature, rain water, salt water spray, as well as other environmental considerations, require the\u00a0<a href=\"https:\/\/www.prophotonix.com\/led-and-laser-products\/led-products\/led-line-lights\/\">LED line light<\/a>\u00a0to be environmentally sealed and robust enough to withstand external conditions.<\/li>\n<\/ul>\n<ul>\n<li><strong data-redactor-tag=\"strong\">Intensity challenge<br \/>\n<\/strong>Unlike a factory production line where the lighting can be placed very close to the target, a safe standoff distance is required, to allow different sizes of containers to pass easily through the system.<\/li>\n<li><strong data-redactor-tag=\"strong\">Length<br \/>\n<\/strong>The\u00a0<a href=\"https:\/\/www.prophotonix.com\/led-and-laser-products\/led-products\/led-line-lights\/\">LED line light<\/a>\u00a0must also be long enough to illuminate the entire side of the container for the OCR system to properly work.<\/li>\n<\/ul>\n<figure id=\"attachment_1339\" aria-describedby=\"caption-attachment-1339\" style=\"width: 300px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"wp-image-1339 size-medium\" src=\"https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-300x225.jpg 300w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-768x576.jpg 768w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-1024x768.jpg 1024w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-200x150.jpg 200w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-840x630.jpg 840w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4-107x80.jpg 107w, https:\/\/www.prophotonix.com\/wp-content\/uploads\/2017\/12\/Lotus_4.4.jpg 2048w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-1339\" class=\"wp-caption-text\">Figure 1.

The use of\u00a0<a href=\"https:\/\/www.prophotonix.com\/led-and-laser-products\/led-products\/led-line-lights\/\">LED Line lights<\/a>\u00a0in container inspection systems allows for the automation at shipping terminals (air, sea, road and land) to increase recognition and inspection of the huge volumes of cargo containers passing through the shipping terminals each year.
