| Summary: | 碩士 === 國立中興大學 === 精密工程學系所 === 103 === Human’s eyes perceive the color and images around environment, which are gained by visible wave of electromagnetic spectrum. However, there is much important information like high-voltage discharge, water pollution, insect pests control and fruit sweetness, which are gained by invisible wave of spectrum. Therefore, traditional scanning and filtering spectrum analyzer’s major function is designed for reading optical information, but both of them had some defects such as low speed, complex structure, high cost and large data. In this thesis, we want to improve these situations and propose a new method of spectrum analyzer which is high speed, low cost, simple structure, little data. The new structure of transmission combines light collection of fiber with cross sight of line, which uses reflect mirror and transmission fiber to capture spectrum of point image. In addition to, it can synchronize point image and spectral value. In the future, if the structure can be developed and produced successfully, it will not only be used to professional work but also enter domesticity to enhance quality of life.
