Publication number: 20090002713Abstract: There is provided an optical coherent tomography device capable of enlarging a measurement range by removing the affect of a folded image. The device includes an optical phase modulator (14) enabling operation amplifiers (17, 18) and a calculation control device (21) to measure a first intensity as a cosine function for the wave number and a second intensity as a sine function or inverse code function for the wave number from the intensity of the output light multiplexed by a third coupler (16). The calculation control device (21) is based on a first intensity set and a second intensity set of the output light by the optical phase modulator (14) measured by the operation amplifiers (17, 18) and the like, so as to suppress generation of a folded image and identify reflection or a backscattering position and a reflection intensity or a back scattering intensity of the measurement light for the irradiation direction of the measurement light in the measurement object.Type: ApplicationFiled: January 19, 2006Publication date: January 1, 2009Applicants: SCHOOL JURIDICAL PERSON KITASATO GAKUEN, NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Kohji Ohbayashi, Kimiya Shimizu, Takeo Miyazawa, Ryoko Yoshimura, Hiroyuki Ishii

Patent number: 5357294Abstract: A method for visually representing for easy analysis the relations between a plurality of cornea-operated patients' tendencies over time to astigmatism on the one hand, and the surgical techniques employed in the operations on the other. A plurality of diopter data matrices are generated about the multiple corneas having different conditions. An arithmetic mean value of each of the components constituting the data matrices is calculated so as to prepare a mean value matrix. A standard deviation of each of the components is calculated using the mean value matrix and the data matrices so as to prepare a standard deviation matrix. The mean value matrix and the standard deviation matrix are displayed in relevant positions on a cornea map using any of color pallets and graphic patterns associated with the arithmetic mean value and standard deviation of the components.Type: GrantFiled: July 9, 1993Date of Patent: October 18, 1994Inventors: Kimiya Shimizu, Shunichi Tanaka
