Embodiment Construction

[0018] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific figures.

[0019] like figure 1 , figure 2 As shown in the figure, a scanning optical imaging system based on CCD and PMT technology and suitable for observing the surface quality of coating test plates, includes a manuscript table for placing scanned originals, and there are ruler lines around the manuscript table to facilitate the placement of manuscripts , and can determine the scanning size of the original in time. There is a plate glass in the middle of the original table, and there is a cover on the original table to press the original to be scanned to prevent the leakage of the scanning light. The optical imaging part, the mechanical transmission part that drives the movement of the optical imaging part, and the photoelectric conversion part used t...

Abstract

The invention relates to a scanning type optical imaging system for observing surface quality of a coating test panel, which is developed based on CCD (Charge Coupled Device) and PMT (Photomultiplier Tube) technologies. According to the scanning type optical imaging system disclosed by the invention, a connecting technology of multiple lenses is adopted, a working image captured by a CCD is converted into a digital signal, the digital signal is then subjected to various digital operations, thus the character of a workpiece can be extracted, an illumination unit adopts various illumination modes, and illuminators can be flexibly switched; and for an object in strong light reflection, a part hoped to be observed can be more clearly displayed after reflected light is removed according to an algorithm. The scanning type optical imaging system disclosed by the invention has the beneficial effects that the illumination transmission speed is increased, the situation of the surface quality of a test panel in a coating industry can be accurately displayed and measured, and a basis is provided for the research and development of a surface treatment technology and the quality improvement.

Description

technical field [0001] The invention relates to the field of scanning technology, in particular to a scanning optical imaging system developed based on CCD and PMT technology and suitable for observing the surface quality of a coating test plate. Background technique [0002] A scanner is an external computer equipment that captures images and converts them into digital input devices that the computer can display, edit, store and output. Photographs, text pages, drawings, art drawings, photographic negatives, film films, and even three-dimensional objects such as textiles, sign panels, and printed board samples can be used as scanning objects to extract and convert original lines, graphics, text, photos, planes. The physical object is converted into a device that can be edited and added to the file. It is an input device that is widely used in computers. As a high-tech product integrating optoelectronics and mechanics, it has developed rapidly with its unique digital "image...
