As the rapid development of modern manufacturing industry, the large manufacturing industry such as aerospace, car raised taller requirement to quality control, and because the product of these industries is general big and heavy, often need to solve quality problem in real time in the spot. Be based on this kind of demand just about, come nearly 20 years all sorts of portable optics are three-dimensional measure a technology to come out in succession, among them structural light is three-dimensional because have portable sex,measure a technology strong, measure speed fast, measure precision advanced advantage, already became use a most extensive kind at present three-dimensional measure a technology [1] . Structural light is three-dimensional measure a technology to develop current situation 　 1985, be located in the M of German Munich-Karlsfeld.

A.

N.

Optics measures technical center to take the lead in using phase shift to interfere a law (Phase Shift Interferometry, PSI) came true to be out of shape measure and oscillatory analysis [2] . 1986, the researcher Dr of this center.

Breuckmann introduces PSI technology three-dimensional form appearance to measure, formed a kind of new three-dimensional form appearance to measure a technology: Phasic measure outline art (PMP) . Established oneself laboratory, pursue the research of this respect technology technically, come to what rolled out different type in succession nearly 20 years survey a system, detect in industry, cultural relic digitlization, human body is measured waited for many domains to receive wide application [3-5] . Divide Dr.

Beyond Breuckmann, dr.

Steinbichler[6-9] , Dr.

The Reinhold Ritter of Wolf[10] and German Technical University Of Braunschweig is taught [11-12] , also be structural light three-dimensional the pioneer that measures technical domain. They are going up 90 time established the century respectively Steinbichler GmbH, Dr.

Wolf GmbH and GOM GmbH, rolled out light of much money structure in succession three-dimensional survey a system. Come nearly 10 years, the much place college such as university of Tsinghua university of home, Hua Zhongke ability, Shanghai traffic university, Xi'an traffic university also is dogging, digest, on the foundation that absorbs foreign advanced technique, measured a technology to undertake the system studies to structural light, rolled out commercial system, be like: The OKIO-II of limited company of science and technology of Beijing Tian Yuansan dimension three-dimensional scanner, the light of PowerScanner series construction of university of Hua Zhongke ability is three-dimensional the 3DSS that measures number of system, Shanghai to create limited company of Electromechanical science and technology is integrated model three-dimensional scanner. From afore-mentioned domestic and international development the circumstance is knowable, structural light is three-dimensional it is relatively mature already to measure a technology, but in phasic computation and systematic parameter demarcate respect of 2 crucial technologies still has a lot of problems to need to solve, for this the article drafts crucial to these 2 technology to undertake treatise, be in to its the actual application circumstance in aviation industry undertakes introductory. Structural light is three-dimensional measure a technology to be in aviation mould design and the applied structure light in making are three-dimensional those who measure a technology to serve as a kind of fast, portable, high accuracy is three-dimensional measure a technology, be versed in in car, aviation, mould, medical treatment and rehabilitation design of Cheng, electric home appliancesCNC Milling CNC Machining
