Linear scanning of surfaces

Linear scanning systems of surfaces

We design and develop linear scanning systems suitable for the acquisition and analysis of surfaces. line scan differs from matrix camera capture, where single frame is made up of a single “line”, just as it occurs when scanning an ordinary sheet of paper with a document scanner. In fact, linear acquisition is suitable for acquiring non-singularized objects moving at a constant speed on a conveyor belt or a roller conveyor. A system of linear acquisition is particularly suitable for the analysis of the production of objects, of important lengths in which a very detailed resolution is required. This is because, unlike classic (matrix) cameras, the resulting image is the composition of many consecutive shots which therefore allow us to obtain much larger images that can contain the entire product.

With the acquisition by means of a line camera, the shooting is carried out for only one image line at a time. The individual acquisitions are then composed by synchronizing them with the movement of the object to be analyzed which flows under the range of action of one or more cameras. During the process of composing the final image, all the acquired lines have all the same conditions: this allows to eliminate all the problems deriving from optical distortion due to the shooting angle. A superior quality recomposed image is therefore obtained, on which it is possible to carry out precise and accurate analyzes thanks to the very high resolution obtained using this technology. If the resolution in width depends on the dimensions of the sensor and the optics used, that along the advancement depends on the speed of movement of the object and the acquisition speed of the linear camera. We use cameras that can reach up to 80kHz this implies that if the progress of the object was 0.8 m/sec we would obtain a resolution of 0.01 mm/px!
