In the concern of the optical imaging system for our apparatus, Fourier optics plays as a key role. In order to improve the precision of the image measurement system in this study, several key components are introduced.Some technologies are also adopted to the measuring apparatus, including the light source selection, the imaging difference between monochromatic and colorful CCD cameras, fine-tuning of the precision for stepping stages, vibration depression of CCD apparatus, ambient temperature monitoring and compensation methods, optimized f-number, the temperature compensation of stage driving motors. In the concern of the precision evaluation for the CCD apparatus, the well-known Gauge R&R analysis is used. In the concern of the calibration and verification for the CCD apparatus, the SPC system was involved for product quality monitoring. Finally, we make the comparison of measurement data with that from national-standard apparatuses, including ITRI’s and Mithutoyo’s setup. en_US DC.subject 等光程條件 zh_TW DC.subject 重複性 zh_TW DC.subject 取樣定理 zh_TW DC.subject 截止頻率 zh_TW DC.subject 孔徑光闌 zh_TW DC.subject Isoplanatic condition en_US DC.subject Repeatability en_US DC.subject Sampling theorem en_US DC.subject Cutoff frequency en_US DC.subject Aperture Stop en_US DC.title CCD 量測儀器之研究與探討 zh_TW dc.language.iso zh-TW zh-TW DC.title CCD Measurement Apparatus Design and Review en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
