【Abstract】 A highly sensitive multi-channel and synchronous p O 2 analysis system was developed, by using new chip and designing software with Visual C++ and Matlab, we greatly reduce the hardware cost and provide a full function workstation that is very convenient and economic. While providing a lower cost solution, it also provides performance and space improvements. On the same time, we employ digital correlation technique to improve signal-to-noise rate, and get satisfied results. Compared with other methods that are used to detect p O 2, the apparatus has many advantages, such as low detection limit?high precision?intelligent data processing and compact space. All these make it possible to meet higher application requirement for p O 2 sensor in vivo detection and clinic research.更多还原
