Abstract In this thesis designing and manufacturing of a three dimension laser scanner is put tostudy A component s geometric model which has unknown dimension and levels couldbe present by this machine with a high accuracy in computer designing invironment Tomanufacture such a machine first all the available methods for scanning surfaces witheach other is compared then using laser method as a most precies and skilfull method ischosen Additionally right selection of hardwares in this machine s construction causedhigh reduction of construction s costs comparing with similar samples A software isdesigned for this made laser scanner in this thesis that the operator can controlmachine s performance totally by using this software Availability of this capabilityleads a decrease in number of unnecessary movements One of the most important and critical cases which is expected in this machine is highaccuracy so in this study effective factors on measuring accuracy and error reductionmethod in results of this machine is considered as a main part of this thesis In thesetrails standard length and angle gauges is used in order to impress scanner depth andradiation angle on results Finally errors are reduced by using sub program andsupposing the independence of error effects on each other
