| Popis: |
Laser-Doppler instrument optimized for estimation of red blood cells speed distributions in microvascular bed was developed. The instrument allows for decomposition of laser-Doppler spectra which based on an assumption that the spectrum can be represented as a linear combination of Doppler shift probability distributions. The decomposition procedure requires high signal to noise ratio in measured spectra. We developed the laser-Doppler instrument with signal to nose ratio greater than 80dB which allows for measurements of blood speed distributions in microvasculary system in real time. The hardware and software architecture of the instrument and first results of its validation during in − vivo experiment with postocclusive reactive hyperaemia test are presented. |
