Welcome to Yoshimura Lab.！ In this laboratory, subjects of research on the application of light wave technology to information & communication and medicine are being studied. A paper will be presented at the 2010 International Conference on Image Processing (ICIP2010, IEEE) in The Hong Kong Convention and Exhibition Centre, Hong Kong, China, on Sep. 28, 2010. A paper was presented at the7th International Conference on Optics-photonics Design & Fabrication (ODF'10) in Pacifico Yokohama, Japan, on Apr. 20, 2010. Two papers were presented at the 57th Spring Meetings of the Japan Society of Applied Physics and Related Societies, in Tokai University, Japan, on Mar. 17 and 18, 2010. A paper was presented at the Optics & Photonics Japan 2009, sponsered by The Optical Society of Japan, in the Toki Messe (Niigata Convention Center), Japan, on Nov. 26, 2009. A paper was presented at Eighth Japan-Finland Joint Symposium on Optics in Engineering, in Tokyo University of Science, Japan, on Sep. 4, 2009. A paper (No.7442-26) was presented at Optical Engineering + Applications (Part of SPIE Optics + Photonics 2009), in San Diego, USA, on Aug. 6, 2009. "Development of the high-speed information encryption system by use of the fractional Fourier transform" was selected as the "Research for Promoting Technological Seeds in 2009" supported by the Japan Science and Technology Agency (JST). (Jun. 22, 2009) A review entitled "Encryption technology of image information by use of the fractional Fourier transform" was published in Chemical Engineering, Vol.54. No.5 (2009) in Japanese.
