A Study Of New Track Surface Shape Detector

The impeller machine is widly used in many field, such as spaceflight, aviation, automobile, energy souce and so on. With the require of quality improved of laminae, the precision and efficiency of the measurement become more and more important. At present, the emphasis of research is to use the Three-coordinate Measurement Machine to take measurement in and out of our country, because it has the advantages of wide measurement scope, high precision and high efficiency and so on. The fuction, working efficiency and precision of the Three-coordinate Measurement Machine is closely related to the detector. The emergence of new type of detector will be bound to make the fuctions of the measurement machine more consummate. Therefore, the thesis chooses this research task which have great advantages in application .In this thesis, a new surface shape detector is put forward by the method of analyse and demonstration. Experiment system is degsigned and demonstated in detail. The fuction of the whole body and every part of the program is introduced. The method of experiment is degsigned, the experiment's process is talked about and the data are analysed. Comparing with other track measurement , we draw the conclusion :the track measurement in our reseach has higher resolving power and higher measure precision, so it is worth to study and extend further. Also, the reasons which affect the measurement precision are analysed detailedly and the improved measures are put forward so as to establish the base to make this research to practice.This research content is abroad and deal with many disciplines such asoptics, electron, computer, control, measurement and image process and so on. The new surface shape detector provide a practical and effecitive method to measure the object's surface shape. In the experiment, the detector is proved to have the advantage that it do not injure the suface in measurement, have high degree of automation, have high measurement precision ,and can make far distance measurement. This detector can take the measurement not only of the lamina's surface shape but also of varied surface with diffuse reflection. It can not only set on the Three-dimensional Coordinate Measurement Machine but also combine with other machine such as Interferometer to take measurement, so it has broad foreground and high application value.
