碩士 === 國立交通大學 === 光電工程研究所 === 106 === The characteristic of hyperspectral image of analyze object composition is widely used in telemetry analysis, land planning, mineral detection and biomedi-cal fields. Measurement system is also gradually developed from point scan to two-dimensional snapshot imaging. The applicable spectrum also evolves to UV light and infrared light with the application requirements. In the future, hypersp-ectral image will have great potential for development in composition analysis, pathological testing and surgical assistance. In this paper, we design a low cost hyperspectral imager used in visible light band with the existing development of hyperspectral imager as a benchmark. Use the Approximate telecentric design to achieve the characteristics of elastic object distance. Add the internal scanning system to improve the shortcomings of previous linear scan spectrometer that need to move the entire instrument, and have good imaging quality that the spectral resolution of 1.3nm, the spatial reso-lution of 0.4mm. Develop automated measurement systems to speed up measur-ement and reduce the error in human operation. Finally, hyperspectral image analysis is used to detect the composition of the object, which is applied to the food safety inspection to establish the judgment index.
