The analysis considers the fresh new remote being able to access off psychological guidance (we

e., heart rate, SPOdos) by using ambient light. The performance of the system proposed shows good agreement with the result measured by a commercial pulse oximeter sensor. In the system, two CCD, being equidistant from the tested face, are used to capture the same section on the face. So debugging and adjustment is necessary. The adoption of the narrow band-filter allows the device be free from any interference produced by the ambient light of other band. Also, the FWHM of the narrow filters adopted in this paper is 10nm, increasing the tolerance of the system to light source. When the grey value of image captured by CCD is below 50, an approximately stable artificial light source, whose spectral range is wide enough to cover the needed wavelengths of 520nm and 660nm, is needed. In our experiments, a lamp with light diffusion plate is used for supplementing light under inadequate lighting condition. Read the rest of this entry »
