Claim:
1. A method of measuring a glucose concentration of a measuring device comprising: generating a first beam including polarizing components, which are applied by a polarizer; generating a second beam which is a wavelength swept laser beam having a coherence length previously set; sending a mixed beam obtained by mixing the first and second beams to an eye in a first direction; measuring a net optical path length by interference between a reflection beam which is reflected from a reference reflector and a first output beam being output returning from the eye in a first direction, wherein the measuring the net optical path length comprises: measuring the rotation amount of a polarization plane from a second output beam being output in a second direction having a specific angle with respect to the first direction; and measuring a glucose concentration of an aqueous humor on the basis of the net optical path length and the rotation amount of the polarization plane.
