<P>PROBLEM TO BE SOLVED: To provide a molecular composition measuring method and device capable of measuring the molecular composition or concentration of a sample or of protein in the anterior chamber of a human eye with high reliability, in non-contact and non-invasive manner. <P>SOLUTION: Laser beam fluxes of different wavelengths are emitted from a wavelength variable laser light source 10 into the anterior chamber 21 of the human eye including molecules of protein of albumin and globulin. The scattering light from the protein molecules is received by a detector 8, and an autocorrelation function of the scattering light signal is found by a correlator 9. A computing device 11 computes the concentration of albumin and of globulin or the ratio between the concentrations based on the autocorrelation function of the scattering light signals of albumin and globulin irradiated with the laser beam fluxes of different wavelengths respectively. With this structure, the concentrations of albumin and globulin, or the ratio between the concentrations can be reliably measured in non-contact and non-invasive manner. <P>COPYRIGHT: (C)2011,JPO&INPIT |
