Patent ID: 8545404

Claim:
An eyeball tissue characteristic frequency measurement device comprising: an air flow spray device for spraying an air flow to a cornea of an eye to be examined and deforming the cornea; a cornea deformation amount measurement device for measuring deformation of the cornea caused by the air flow from the air flow spray unit along with elapsed time from the start of the air flow spray; a Fourier analysis unit performing Fourier analysis on a relationship between a deformation amount of the cornea obtained by the cornea deformation amount measurement unit and the elapsed time; and an eyeball tissue characteristic frequency operation unit obtaining an characteristic frequency of each constituent tissue of an eyeball based on a Fourier analysis result obtained by the Fourier analysis unit wherein the Fourier analysis unit includes a numerical simulation result preserving unit preserving a numerical simulation result of the eyeball deformation, and a pattern classification unit performing pattern classification for determining to which tissue characteristic frequency of the eyeball a Fourier-analyzed time function corresponds.
