MCU System Basing On Micro Spectrometer

As one of the typical MOEMS, the micro-spectrometer has many advantages compared with traditional spectrometers. It can be used in many areas. For these reasons, research on the spectrometer has become one of the research focuses worldwide. To make micro-spectrometer more practical in applications, it is necessary to do some research on the signal collecting and displaying system which can work with micro-spectrometer to get a higher capability and lower the price. With the support of the Chinese National Nature Science Fund, we do some research work on the designing of signal collecting and displaying system of the refraction-diffraction hybrid integrated micro spectrometer basing on MCU (micro control unit). To do that, we have to have a deep comprehension on the principle of the refraction-diffraction hybrid integrated micro spectrometer. At the same time, we also learn some basic knowledge about system design with, analog electronics and digital electronics. Work finished is listed as following. ①with a deep comprehension on the principle of the refraction-diffraction hybrid integrated micro spectrometer, we refer to a lot of literature and data and put forward a scheme of the design of signal collecting and displaying system basing on MCU to work with the refraction-diffraction hybrid integrated micro spectrometer. ②After a research work on the characteristic of the electronic output of the refraction-diffraction hybrid integrated micro spectrometer, combined with comprehension on the signal sampling theory , we finish the design signal collecting and displaying system basing on MCU. ③Make the corresponding program to realize signal collecting and displaying. ④Learn the drawing technique and the anti-jamming technology of the mixed signal PCB (printed circuit board) and draw the PCB of the signal collecting and displaying system basing on MCU mentioned above. ⑤Finish hardware and software debug of the whole system.
