The invention discloses a quick
biological tissue optical characteristic parameter measurement method based on short-pulse
laser reflection
signal peak inversion and belongs to the technical field of
biological tissue optical characteristic parameter measurement. The problem that the
response time for the conventional
biological tissue optical characteristic parameter measurement is long is solved. The method comprises the steps of measuring a
peak value Rmax of a
time domain semispherical reflection
signal on the surface of a sample block to be measured, changing a pulse width tp of a
laser device to obtain n groups of semispherical reflection
signal peak values Rmax,i according to the former measuring method, setting the scattering
albedo Omega of a sample to be measured and an asymmetric factor g of the sample to be measured, and obtaining undetermined coefficients a and b through an experience formula; obtaining estimated values Rmax,i of the n groups of semispherical reflection signal peak values, and performing least-square on estimated values Rmax,i of
time domain semispherical reflection signal peak values and
time domain semispherical reflection signals Rmax,i corresponding to the estimated values Rmax,i of the signal peak values to obtain a difference value; judging whether the least-square difference value is smaller than a threshold value Epsilon, if the least-square difference value is smaller than the threshold value Epsilon, implementing quick measurement on the biological tissue optical characteristic parameter based on the short-pulse
laser reflection signal peak inversion, otherwise, continuing performing measurement. The quick biological tissue optical characteristic parameter measurement method is suitable for biological tissue optical characteristic parameter measurement.
