Abstract: An ophthalmic imaging system includes a light source, focusing optics, compensating optics, and a computer that coordinates both of the optics to optimize the Diffraction Limited Point Spread Function (DL-PSF) of the imaging light beam. In detail, the compensating optics includes a customized phase plate that provides substantially complete compensation for static aberrations introduced by an eye into the imaging light beam. Further, the computer measures an operational error signal that results from dynamic aberrations. The computer then uses the error signal to control the compensating optics and thereby optimize the DL-PSF by compensating for both static and dynamic aberrations. For an alternate embodiment, an active mirror can be included in the compensating optics to provide additional compensation for the dynamic aberrations.

Abstract: The detection device provides with an optical fiber composed of a core, a clad and a fiber jacket. A grating is applied to the core, and the fiber jacket located at the portion to which the grating is applied is removed so that the clad is in contact with a fuel fed to an injector of a vehicle. The detection device also provides with a light source for incidence of a light in a range of clad mode wavelength to the optical fiber, and a light-sensitive part for detecting an intensity of the light transmitting through the region to which the grating is applied. The optical fiber, light source and light-sensitive part are held in a conduit disposed in a fuel tank or between a fuel pump and the injector of the vehicle.
