レーザースペックル現象を利用した眼底血流測定 (III)

抄録

The laser speckle method is further studied for evaluating the blood flow at the ocular fundus of normal human volunteers on the basis of the photon correlation technique. The time-correlation length τ_c of the photon correlation function varies obviously due to the change of the probe position at the human ocular fundus. This paper also studies the ways of eliminating the effect of eye movements and of estimating the shape of the photon correlation function. The experimental results show that the present method can provide favorably the blood-flow information.
