In this paper, considering the disadvantages of the existing methods that are used to examine a white mouses Eye-Movement and blood flux when it is in vertigo, based on digital research, a new method to do that without damage is put forward. Firstly, after investigating sensors for blood flux, according to Doppler theory and what the project requires, a new skin fibre-optic sensor is designed to detect blood flux without damage. Aiming at the features of blood flux examination and what data communication requires, a transmitting module which transmits blood flux signals from sensor to PC is realized through nRF2401 (a single-chip radio transceiver), singlechip and serial ports on PC. Compared with other wireless communications, it is effective, steady and inexpensive. And then, after this paper analyzing the main disadvantages of traditional analyzing Eye-Movement methods and instruments, the CCD sensor is chose to collect analog image signals of Eye-Movement. These signals are transmitted to PC through a special wireless transmission module for analog image signals and video collector that converts the analog signals to digital signals, the digital image dates are analyzed and processed by PC. Finally, the on-line detection of Eye-Movement and blood flux is carried out in room circumstance, and system software is designed to gather the data andachieve the result with VC++6.0. It realizes transmitting the data through RS232, obtaining the images, processing the image data and analyzing the results.
