The quality specifications for products and the materials used in them are becoming ever more demanding. The solution to the many visual inspection quality assurance (QA) problems is the use of automatic in-line surface inspection systems. These need to achieve uniform product quality at high throughput speeds. As a result, there is a need for systems that allow 100% in-line testing of materials and surfaces. To reach this goal laser technology integrated with computer control technology provides a useful solution. In this work, a high speed, low cost, and high accuracy non-contact laser scanning inspection system is developed. The system is capable of measuring the thickness of solid, non-transparent objects using the principle of laser-optical triangulation. Measurement accuracies and repeatabilities to the micrometer level are achieved with the developed system.
