Research On Embedded Optical Signal Data Acquisition And Technology Of Human-Computer Interaction

With the development of science and technology, the technology of photoelectric conversion and data acquisition has been widely used in industrial production.Therefore, Optical detection and optical information processing teaching is becoming more and more attention to science and engineering colleges, and practice of teaching put forward higher requirements. To build a complete optical information processing optical detection and teaching platform, this topic is proposed embedded optical and electrical properties measurement system,in regard to optical detection system research has practical significance.The first issue analysises, researches various principles and characteristics of optoelectronic devices, and photoelectric sensor for a variety of basic electrical signal output photoelectric detection of pre-processing circuit is completed. To achieve optical signal data acquisition. Using the ARM9 core embedded systems, the DSP and ARM interface technology to carry though high-speed optical signal data acquisition. quantitative experimental results show by ARM9 interface design, for this reason human-computer interaction function is complished better.
