Biological information measurement device, biological information measurement method, and computer-readable recording medium

A biological information measurement method executed by a computer, the method comprising:

• calculating a scattering rate of light at an interface between a medium present in a biological object or in a specimen and a particle included in the medium based on received-light intensity of light irradiated onto the biological object or onto the specimen and received via the biological object or via the specimen;
• and
• calculating the concentration index as biological information calculating performing correction in form of subtracting the calculated scattering rate of light based on a correlation stored in a memory and established between the scattering rate of light at the interface and a concentration index corresponding to concentration of a target substance that is different from the particle included in the medium, wherein
• in the calculating the scattering rate of light, calculating the scattering rate of light based on base received-light intensity R0 that represents received-light intensity of light when scattering in the medium is minimum or substantially equal to zero, is used.

A non-transitory computer-readable recording medium on which an executable program causing a processor of a computer to execute:

• calculating a scattering rate of light at an interface between a medium present in a biological object or in a specimen and a particle included in the medium based on received-light intensity of light irradiated onto the biological object or onto the specimen and received via the biological object or via the specimen;
• and
• calculating, based on a correlation between the scattering rate of the light at the interface and a concentration index corresponding to concentration of a target substance that is different from the particle included in the medium, the concentration index corresponding to the calculated scattering rate of the light, wherein
• in the calculating the scattering rate of light, calculating the scattering rate of light based on base received-light intensity R0 that represents received-light intensity of light when scattering in the medium is minimum or substantially equal to zero, is used.
