碩士 === 國立中央大學 === 光機電工程研究所 === 102 === In this thesis, the optical module of 2D image measurement system with high light collimation, high illumination uniformity, and large illuminate area is designed and verified. For two kinds of light sources: light-emitting diode (LED) and LASER, the research targets are taken as: the operating range in the distance 100mm~300mm , operating area 70mm×70mm , half of the full-width half-maximum (FWHM) angle  2.00, and the illumination uniformity70.0%. For the case of LED light source, the results of simulation and experiment are full-width half-maximum (FWHM) angle 1.23°、illumination uniformity 78.8% and full-width half-maximum (FWHM) angle  0.77°、illumination uniformity 78.1%. For the case of LASER light source, the result of simulation is full-width half-maximum (FWHM) angle  0.39°、illumination uniformity 71.0% ,while the result of experiment is full-width half-maximum angle (FWHM)  0.28°、illumination uniformity  69.6% when the operating range in the distance 100mm~300mm is 70mm×70mm, respectively. In sum, it can be realized that the result achieves the expected design.
