  • Patent number: 9029068
    Abstract: Allowing the rate of phase change to be controlled at the time period of phonons (approx. 270 fs) for the purpose of achieving a substantially higher recording-erasing speed compared to what can be achieved with conventional technologies relating to optical recording media using phase change. A femtosecond pulse laser is shaped into pulse trains each having a first pulse and a second pulse using a Michelson interferometer, and the time interval of first and second pulses is matched with the time period of lattice vibration of a material constituting the phase change recording film to be irradiated, thereby inducing phase change.

  • Publication number: 20150009507
    Abstract: In an embodiment, a computer 16, which generates tomographic images based on spectral interference signals detected by a light detector 15 from overlaid reference light emitted by a swept-source type light source 2 of a SS-OCT, split, and then reflected by a fixed reference mirror 8 on one hand and object light reflected by an object to be measured 6 on the other, is caused to function to apply rough correction using a first correction means and then apply detailed correction using a second correction means, to stabilize the phases of the SS-OCT. The phases can be stabilized by eliminating, without adding any expensive, complex hardware, the jitter between the wavelength scanning of a light source of SS-OCT and the timing of collecting the scan data with the light detector as spectral interference signals.
