碩士 === 華梵大學 === 機電工程研究所 === 94 === A micro spectrometer system its main host to have the spectrometer (to contain micro diffraction grating,CMOS linear image sensor ,the driver/amplifier circuit(C5463), the pulse generator（C5945）, the delay circuit（74LS123）, the AD/DA card（ACL8112HG）and computer. The spectrometer is expensively approximately composes this system 40%. When the spectrometer has new also the price cheap product, whether this time this system still could use and its changes in accordance to it method is extremely important. Therefore this article studies the goal; Grinds analyzed the signal which the existing micro spectrometer system picks up, enable this system to have the new product in the main module (spectrometer) to be published time how still could use. Has the micro spectrometer system its pulse generator to use HAMAMATSU Corporation to make, the model is pulse wave of producer the C5945, the affiliation by the experimental understanding and the analysis digital logic circuit which designs by TTL (Transistor- Transistor Logic) substitutes by CPLD(Complex Programmable Logic Device) on the C5945 electric circuit board. If CPLD matches with components of by the correlation then designs a new pulse generator.However the spectrometer does change the pulse generator to be able independently to design the development, meets its need to achieve comfortable the goal.
